strqget(9r)
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
  queue_pointer
      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 *.

  what
      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.

  pri Specifies the priority of the request.

  val Specifies the value for the requested member.

DESCRIPTION
  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;

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