Returns the address of a 64-bit signal array. A 32-bit signal array and a mechanism array are passed to a condition handler when it is called. $SIGNAL_ARRAY_64 provides the address of the 64-bit signal array, which might be required for programs that use 64-bit address space.This service accepts 64-bit addresses.
SYS$SIGNAL_ARRAY_64 mcharg, sigarg_64
int sys$signal_array_64 (unsigned __int64 mcharg, unsigned __int64 sigarg_64);
mcharg
OpenVMS usage: mechanism array type: vector quadword (unsigned) access: read only mechanism: by 32- or 64-bit reference, array reference
The mechanism array. The mcharg argument is the 32- or 64-bit address of this array, which was passed to the condition handler. $SIGNAL_ARRAY_64 uses this structure to determine the 64-bit signal array address.sigarg_64
OpenVMS usage: 64-bit signal array type: vector quadword (unsigned) access: write only mechanism: by 32- or 64-bit reference, array reference
The 32- or 64-bit address of the 64-bit signal array is returned in this argument.
$SIGNAL_ARRAY_64 provides the address of the 64-bit version of the signal array for condition handlers that need it. It is normally needed only by applications that use 64-bit address space and want to handle errors involving addresses in that region.For example, if an access violation occurs on a 64-bit address, the 32-bit signal array passed to the handler will contain only the low 32 bits of the effective address, because each entry is a longword. The 64-bit signal array, which can be obtained using this service, contains quadword entries, so the 64-bit address can be fully expressed.
None
None
$PUTMSG, which accepts either a 32-bit or 64-bit signal array as an argument.
SS$_NORMAL The service completed succesfully. SS$_ACCVIO The sigarg_64 argument cannot be written. SS$_BADPARAM The mcharg argument is not a mechanism array in the expected format.
Writes a user-specified message to the system error log file, preceding it with the date and time.
SYS$SNDERR msgbuf
int sys$snderr (void *msgbuf);
msgbuf
OpenVMS usage: char_string type: character-coded text string access: read only mechanism: by descriptor--fixed-length string descriptor
Message to be written to the error log file. The msgbuf argument is the address of a character string descriptor pointing to the message text.
The Send Message to Error Logger service writes a user-specified message to the system error log file, preceding it with the date and time. The $SNDERR service requires system dynamic memory.To send a message to the error log file, the calling process must have BUGCHK privilege.

Creates, stops, and manages queues and the batch and print jobs in those queues. The $SNDJBC service completes asynchronously; to synchronize the completion of most operations, use the Send to Job Controller and Wait ($SNDJBCW) service.
SYS$SNDJBC [efn] ,func [,nullarg] [,itmlst] [,iosb] [,astadr] [,astprm]
int sys$sndjbc (unsigned int efn, unsigned short int func, unsigned int nullarg, void *itmlst, struct _iosb *iosb, void (*astadr)(__unknown_params), int astprm);
efn
OpenVMS usage: ef_number type: longword (unsigned) access: read only mechanism: by value
Number of the event flag to be set when $SNDJBC completes. The efn argument is a longword containing this number; however, $SNDJBC uses only the low-order byte.When you queue the request, $SNDJBC clears the specified event flag (or event flag 0 if efn was not specified). Then, when the operation completes, $SNDJBC sets the specified event flag (or event flag 0).
func
OpenVMS usage: function_code type: word (unsigned) access: read only mechanism: by value
Function code specifying the function that $SNDJBC is to perform. The func argument is a word containing this function code. The $SJCDEF macro defines the names of each function code.You can specify only one function code in a single call to $SNDJBC. Most function codes require or allow for additional information to be passed in the call. You pass this information by using the itmlst argument, which specifies a list of one or more item descriptors. Each item descriptor in turn specifies an item code, which modifies, restricts, or otherwise affects the action designated by the function code.
nullarg
OpenVMS usage: null_arg type: longword (unsigned) access: read only mechanism: by value
Placeholding argument reserved to HP.
itmlst
OpenVMS usage: item_list_3 type: longword (unsigned) access: read only mechanism: by reference
Item list supplying information to be used in performing the function specified by the func argument. The itmlst argument is the address of the item list. The item list consists of one or more item descriptors, each of which specifies an item code. The item list is terminated by an item code of 0 or by a longword of 0. The following diagram depicts the structure of a single item descriptor:
The following table defines the item descriptor fields:
| Descriptor Field | Definition |
|---|---|
| Buffer length | A word specifying the length of the buffer; the buffer either supplies information to be used by $SNDJBC or receives information from $SNDJBC. The required length of the buffer varies, depending on the item code specified, and is given in the description of each item code. |
| Item code | A word containing an item code, which identifies the nature of the information supplied for use by $SNDJBC or received from $SNDJBC. Each item code has a symbolic name. The $SJCDEF macro defines these symbol names. |
| Buffer address | A longword containing the address of the buffer that specifies or receives the information. |
| Return length address | A longword containing the address of a word to receive the length (in bytes) of information returned by $SNDJBC. If you specify this address as 0, no length is returned. |
The item codes' symbolic names have the following format:
|
SJC$_code |
There are three types of item code:
Several item codes specify a queue name, form name, or characteristic name. For these item codes, the buffer must specify a string containing from 1 to 31 characters, exclusive of spaces, tabs, and null characters, which are ignored. Allowable characters in the string are uppercase alphabetic characters, lowercase alphabetic characters (which are converted to uppercase), numeric characters, the dollar sign ($), and the underscore (_).
| OpenVMS usage: | io_status_block |
| type: | quadword (unsigned) |
| access: | write only |
| mechanism: | by reference |
At request initiation, $SNDJBC sets the value of the quadword I/O status block to 0. When the requested operation completes, $SNDJBC writes a condition value in the first longword of the I/O status block. It writes the value 0 into the second longword; this longword is unused and reserved for future use.
The condition values returned by $SNDJBC in the I/O status block are usually condition values from the JBC facility. These condition values are defined by the $JBCMSGDEF macro. In some cases, the condition value returned by $SNDJBC can be an error return from a system service or an OpenVMS RMS service that is used in executing the request. For the SJC$_SYNCHRONIZE_JOB request, the condition value returned is the completion status of the requested job.
The condition values returned from the JBC facility are listed in the Condition Values Returned in the I/O Status Block section.
Though this argument is optional, HP strongly recommends that you specify it, for the following reasons:
| OpenVMS usage: | ast_procedure |
| type: | procedure value |
| access: | call without stack unwinding |
| mechanism: | by reference |
If specified, the AST routine executes at the same access mode as the caller of $SNDJBC.
| OpenVMS usage: | user_arg |
| type: | longword (unsigned) |
| access: | read only |
| mechanism: | by value |
SJC$_ABORT_JOB
Aborts the execution of the current job from an output execution queue or the job you specified from a batch queue. By default, the job is deleted. However, for a restartable job, you can requeue it to the same queue or to another queue.You must specify one of the following input value item codes:
SJC$_ENTRY_NUMBER
SJC$_QUEUEYou must specify the following input value item code for batch jobs:
SJC$_ENTRY_NUMBERYou can specify the following optional input value or Boolean item codes:
SJC$_DESTINATION_QUEUE --- SJC$_HOLD SJC$_NO_HOLD SJC$_PRIORITY --- SJC$_REQUEUE --- SJC$_ADD_FILE
Adds a file to the open job owned by the requesting process. You use this operation as part of a sequence of calls to the $SNDJBC service to create a job with one or more files. The first call in the sequence specifies the SJC$_CREATE_JOB operation to create an open job. Each subsequent SJC$_ADD_FILE request associates an additional file with the job. Finally, you make an SJC$_CLOSE_JOB request to complete the batch or print job specification.To create a job that contains only one file, you can make a single call to $SNDJBC that specifies the SJC$_ENTER_FILE function code.
