Returns the number of system resource allocation domains (RADs) that have available resources.
Standard C library (libc.a)
#include <sys/rset.h>
int rs_numrads(rset, sdl, flags)
rsethandle_t rset;
unsigned int sdl;
unsigned int flags;The rs_numrads subroutine returns the number of system RADs at system detail level sdl, that have available resources contained in the resource set identified by the rset parameter.
The number of atomic RADs contained in the rset parameter is returned if the sdl parameter is equal to the maximum system detail level.
| Item | Description |
|---|---|
| rset | Specifies the resource set handle for the resource set being queried. |
| sdl | Specifies the system detail level in which the caller is interested. |
| flags | Reserved for future use. Specify as 0. |
If successful, the number of available RADs at system detail level sdl, that have resources contained in the specified resource set is returned. If unsuccessful, a value of -1 is returned and the errno global variable is set to indicate the error.
