IP_QueueWrite
IP_QueueWrite — writes a message to a queue.
Syntax
#include <cogent.h>
int IP_QueueWrite( | int | qid, |
| | void* | msg, |
| | int | length, |
| | int | priority); |
Arguments
- qid
- A queue ID.
- msg
- The message buffer to be sent to the queue.
- length
- The length in bytes of
msg.
- priority
- The priority of this message.
Returns
0 on success,
or -1 on failure and
errno is set.
Description
This function writes a
message to the queue specified by qid. Higher
priority numbers are treated as having a higher
priority. Priority ordering is not currently implemented. A single
write to the queue is limited by the operating system. Queue messages
transmitted in a single write will never be broken apart or
concatenated with other messages.
