            .SH "DESCRIPTION"
                .PP glGetFragDataLocation retrieves the assigned color number binding for the user-defined varying out variable name for program program. program must have previously been linked. name must be a null-terminated string. If name is not the name of an active user-defined varying out fragment shader variable within program, -1 will be returned.

            .SH "ERRORS"
                .PP GL_INVALID_OPERATION is generated if program is not the name of a program object.
