Purpose
This directs all Optimizer output to a
log file.
Synopsis
int XPRS_CC XPRSsetlogfile(XPRSprob prob, const char *filename);
Arguments
|
prob
|
The current problem.
|
|
filename
|
The name of the file to which all output will be directed. If set to NULL, redirection of the output will stop and all screen output will be turned back on (except for DLL users where screen output
is always turned off).
|
Example
The following directs output to the file logfile.log:
XPRSinit(NULL);
XPRScreateprob(&prob);
XPRSsetlogfile(prob,"logfile.log");
Further information
1. It is recommended that a log file be set up for each problem being worked on,
since it provides a means for obtaining any
errors or warnings output by the
Optimizer during the solution process.
2. If output is redirected with XPRSsetlogfile all screen output will be
turned off.
3. Alternatively, an output callback can be defined using
XPRSsetcbmessage, which will be called
every time a line of text is output. Defining a user output callback will turn all screen output
off. To discard all output messages the
OUTPUTLOG integer control can be set to
0.
