[drmaa-wg] Additional error for C binding

Hi, the DRMAA C-binding 1.0 defines an additional parameter for the string length (job_id_out_len) whenever job_id_out is part of the method signature. In the DRMAA spec, this is not considered - the string is simply marked as output argument. I would be interested what kind of error a DRMAA C-library should return of the buffer for the job_id_out parameter is too small: OUT_OF_MEMORY ? INVALID_ARGUMENT ? Regards, Peter.
