NAME
       strqget - General: Obtains information about a queue

SYNOPSIS
       #include <sys/stream.h>

       int strqget(
	       queue_t *queue_pointer,
	       qfields_t what,
	       unsigned char pri,
	       long *val );

ARGUMENTS
       Specifies  a pointer to the queue for which you want to obtain informa‐
       tion. 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.

DESCRIPTION
       The  strqget routine gives modules and drivers a way to obtain informa‐
       tion 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;

RETURN VALUES
       Upon successful completion, strqget returns  the	 value	0  (zero).  On
       failure, strqget returns an error number.
