#include <sys/stream.h> int strqget(queue_t *q, qfields_t what, unsigned char pri, void *valp);
Architecture independent level 1 (DDI/DKI).
The strqget() function gives drivers and modules a way to get information about a queue or a particular band of a queue without directly accessing STREAMS data structures, thus insulating them from changes in the implementation of these data structures from release to release.
On success, 0 is returned and the value of the requested field is stored in the location pointed to by valp. An error number is returned on failure.
The strqget() function can be called from user, interrupt, or kernel context.
