The routine CPXfclose closes files that are used in conjunction with the routines CPXaddfpdest, CPXdelfpdest, and CPXsetlogfile. It is used in the same way as the standard C library function fclose. Files that are opened with the routine CPXfopen must be closed with the routine CPXfclose.

When to use this routine

Call this routine only after the message destinations that use the file pointer have been closed or deleted. Those destinations (such as log files) might be specified by routines such as CPXaddfpdest, CPXdelfpdest, and CPXsetlogfile.

Example

 CPXfclose (fp);
 

See lpex5.c in the CPLEX User's Manual.

The routine returns zero if successful and nonzero if an error occurs. The syntax is identical to the standard C library routine fclose.
