NAME
strqset - change information about a queue or band of the queue SYNOPSIS
#include <sys/stream.h> int strqset(queue_t *q, qfields_t what, unsigned char pri, intptr_t val); INTERFACE LEVEL
Architecture independent level 1 (DDI/DKI). PARAMETERS
q Pointer to the queue. what Field of the queue structure (or the specified priority band) to return information about. Valid values are one of: QHIWAT High water mark. QLOWAT Low water mark. QMAXPSZ Largest packet accepted. QMINPSZ Smallest packet accepted. pri Priority band of interest. val The value for the field to be changed. DESCRIPTION
The strqset() function gives drivers and modules a way to change information about a queue or a particular band of a queue without directly accessing STREAMS data structures. RETURN VALUES
On success, 0 is returned. EINVAL is returned if an undefined attribute is specified. CONTEXT
The strqset() function can be called from user, interrupt, or kernel context. SEE ALSO
strqget(9F), queue(9S) Writing Device Drivers STREAMS Programming Guide NOTES
When lowering existing values, set QMINPSZ before setting QMAXPSZ; when raising existing values, set QMAXPSZ before setting QMINPSZ. SunOS 5.11 16 Jan 2006 strqset(9F)
