canput
canput(9F) Kernel Functions for Drivers canput(9F)
NAME
canput - test for room in a message queue
SYNOPSIS
#include <sys/stream.h>
int canput(queue_t *q);
INTERFACE LEVEL
Architecture independent level 1 (DDI/DKI).
PARAMETERS
q Pointer to the message queue.
DESCRIPTION
canput() searches through the stream (starting at q) until it finds a queue containing a service routine where the message can be enqueued,
or until it reaches the end of the stream. If found, the queue containing the service routine is tested to see if there is room for a mes-
sage in the queue.
canputnext(q) and bcanputnext(q, pri) should always be used in preference to canput(q->q_next) and bcanput(q->q_next, pri) respectively.
RETURN VALUES
1 If the message queue is not full.
0 If the queue is full.
CONTEXT
canput() can be called from user or interrupt context.
SEE ALSO
bcanput(9F), bcanputnext(9F), canputnext(9F), putbq(9F), putnext(9F)
Writing Device Drivers
STREAMS Programming Guide
WARNINGS
Drivers are responsible for both testing a queue with canput() and refraining from placing a message on the queue if canput() fails.
