(PHP 4 >= 4.3.0, PHP 5)msg_send --

Send a message to a message queue

Description

bool msg_send (resource queue, int msgtype, mixed message [, bool serialize [, bool blocking [, int &errorcode]]])

msg_send() sends a message of type

msgtype (which MUST be greater than 0) to

the message queue specified by queue.

If the message is too large to fit in the queue, your script will wait

until another process reads messages from the queue and frees enough

space for your message to be sent.

This is called blocking; you can prevent blocking by setting the

optional blocking parameter to FALSE, in which

case msg_send() will immediately return FALSE if the

message is too big for the queue, and set the optional

errorcode to EAGAIN, indicating that you should

try to send your message again a little later on.

The optional serialize controls how the

message is sent. serialize

defaults to TRUE which means that the message is

serialized using the same mechanism as the session module before being

sent to the queue. This allows complex arrays and objects to be sent to

other PHP scripts, or if you are using the WDDX serializer, to any WDDX

compatible client.

Upon successful completion the message queue data structure is updated as

follows: msg_lspid is set to the process-ID of the

calling process, msg_qnum is incremented by 1 and

msg_stime is set to the current time.

msg_receive(),

msg_stat_queue() and
