CPXgeterrorstring

Description

The routine CPXgeterrorstring() returns an error message string corresponding to an error code. Error codes are returned by CPLEX routines when some error occurs.

This routine allows the CPLEX environment parameter to be NULL so that errors caused by the CPXopenCPLEX routine can be translated.

Returns NULL if the error code does not have a corresponding string. Returns a pointer to the parameter buffer if the string does exist. In that case, buffer contains the error message string.

char *CPXgeterrorstring (CPXCENVptr env, int errcode, char *buffer_str);

Arguments

The pointer to the CPLEX environment as returned by CPXopenCPLEX().

The error code to be translated.

A character string buffer of at least 510 characters to hold the error string.

char *errstr; errstr = CPXgeterrorstring (env, errcode, buffer); if ( errstr != NULL ) { printf ("%s\n", buffer); } else { printf ("CPLEX Error %5d: Unknown error code.\n", errcode); }
