5 * DESCRIPTION: *
6 * *
7 * This header file contains the function prototype for the asofyet *
8 * undocumented DosQProcStatus API. It also contains the structure *
9 * definitions that are used in the buffer that is returned by the *
10 * API call. *
11 * *
12 * In order to invoke DosQProcStatus, your .DEF file must contain *
13 * this entry: *
14 * *
15 * IMPORTS DOSQPROCSTATUS=DOSCALLS.154 *
