NM and CM callable.
Writes database and subsystem file records to the user logging file. User
logging (LG) or system supervisor (OP) capability is required.
Syntax
I32 U16A I16 I16 I16
WRITELOG (index, data, length, mode, logstatus);
Parameters
- index
32-bit signed integer by reference (required)
Passes your access to the user logging system. This is the value returned
in the index parameter of the OPENLOG
intrinsic.
- data
16-bit unsigned integer array (required)
Passes the information to be logged. A log record contains 128 half words
of which 119 are available for writing data. The most efficient use of
log file space is to structure arrays with lengths in multiples of 119
half words.
- length
16-bit signed integer by reference (required)
Passes the length of the data in data. A positive value
indicates half words; a negative value indicates bytes. If the length is
greater than 119 half words or 238 bytes, the information in
data is divided into two or more physical log
records.
- mode
16-bit signed integer by reference (required)
Passes a value indicating whether the user logging facility will suspend
the process if it cannot complete the request for service immediately. If
it is not possible to log the transaction and mode is set
to nowait, the WRITELOG intrinsic indicates through
logstatus that it could not complete the request.
Value | Meaning |
0 | Wait |
1 | Nowait |
2 | Write the logging buffer to the disk log file (disk
logging) or the disk buffer file (serial logging) at the first
opportunity. |
- logstatus
16-bit signed integer by reference (required)
Returns one of the following values, indicating the success/failure of
the call:
Value | Meaning |
0 | Successful |
1 | Nowait requested, user logging process busy |
2 | Parameter out of bounds |
4 | Incorrect index parameter passed |
5 | Incorrect mode parameter passed |
9 | Error occurred while writing |
12 | System out of disk space; user logging cannot proceed |
14 | Invalid access |
15 | End-of-file on user log file |
