int QuerySchEnv(struct sethdr *sysi_ptr, int *anslen);
General description
The QuerySchEnv() function provides the ability for an application
to query WLM scheduling environment.
- *sysi_ptr
- Points to a buffer that the service is to return the WLM system
information. The data returned is in the format of the structure
sysi.
- *anslen
- Points to an integer data field that contains the length of
the buffer to return the WLM system information into.
Returned value
If successful, QuerySchEnv() returns 0.
If unsuccessful, QuerySchEnv() returns -1 and sets errno to one
of the following values. If the returned errno and __errno2() indicate
the supplied buffer is too small, the
anslen argument is
updated to contain the length required to hold WLM system information.
