The routine CPXfputs can be used to write output to a file opened with CPXfopen. The purpose of this routine is to allow user-defined output in a file to be interspersed with the output created by using the routines CPXaddfpdest or CPXsetlogfile. The syntax of CPXfputs is the same as the standard C library function fputs.

Example

 CPXfputs ("Solved first problem.\n", fp);
