putctl1(9F) Kernel Functions for Drivers putctl1(9F)NAME
putctl1 - send a control message with a one-byte parameter to a queue
SYNOPSIS
#include <sys/stream.h>
int putctl1(queue_t *q, int type, int p);
INTERFACE LEVEL
Architecture independent level 1 (DDI/DKI).
PARAMETERS
q Queue to which the message is to be sent.
type Type of message.
p One-byte parameter.
DESCRIPTION
putctl1(), like putctl(9F), tests the type argument to make sure a data type has not been specified, and attempts to allocate a message
block. The p parameter can be used, for example, to specify how long the delay will be when an M_DELAY message is being sent. putctl1()
fails if type is M_DATA, M_PROTO, or M_PCPROTO, or if a message block cannot be allocated. If successful, putctl1() calls the put(9E) rou-
tine of the queue pointed to by q with the newly allocated and initialized message.
RETURN VALUES
On success, 1 is returned. 0 is returned if type is a data type, or if a message block cannot be allocated.
CONTEXT
putctl1() can be called from user or interrupt context.
EXAMPLES
See the putctl(9F) function page for an example of putctl1().
