CPXXopenCPLEX and CPXopenCPLEX

The routine CPXXopenCPLEX/CPXopenCPLEX initializes a CPLEX environment.

CPXENVptr CPXXopenCPLEX( int * status_p )

CPXENVptr CPXopenCPLEX( int * status_p )

Description

The routine CPXXopenCPLEX/CPXopenCPLEX initializes a CPLEX environment. The routine CPXXopenCPLEX/CPXopenCPLEX must be the first CPLEX routine called. The routine returns a pointer to a CPLEX environment. This pointer is used as an argument to every other nonadvanced CPLEX routine (except CPXXmsgstr/CPXmsgstr).

Arguments

status_p: A pointer to an integer, where an error code is placed by this routine.

Return

A pointer to the CPLEX environment. If an error occurs, the value NULL is returned. The reason for the error is returned in the variable *status_p. If the routine is successful, then *status_p is 0 (zero).

Example


env = CPXopenCPLEX (&status);
