strqget - General: Obtains information about a queue
#include <sys/stream.h>
int strqget(
queue_t *queue_pointer,
qfields_t what,
unsigned char pri,
long *val );
Specifies a pointer to the queue for which you want to
obtain information. The typedef queue_t is an alternate
name for struct queue_entry *. Specifies which member of
the queue structure to return information about. The valid
values are specified in the qfields enumerated data type.
See the DESCRIPTION section for the definition of this
enumerated data type. Specifies the priority of the
request. Specifies the value for the requested member.
The strqget routine gives modules and drivers a way to
obtain information about a queue or a particular band of a
queue without directly accessing STREAMS data structures.
The values that can be returned are defined in the following
enumerated data type:
typedef enum qfields {
QHIWAT = 0,
QLOWAT = 1,
QMAXPSZ = 2,
QMINPSZ = 3,
QCOUNT = 4,
QFIRST = 5,
QLAST = 6,
QFLAG = 7,
QBAD = 8 } qfields_t;
Upon successful completion, strqget returns the value 0
(zero). On failure, strqget returns an error number.
