|
|---|
| 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 *
