    NAME

    
    
    msgget
    
     - get message queue
    
     
    

    LIBRARY

    Lb libc
    
     
    

    SYNOPSIS

       #include <sys/types.h>

       #include <sys/msg.h>
    int msgget (key_t key int msgflg);
     

    DESCRIPTION

    The msgget ();
    function returns the message queue identifier associated with Fa key . A message queue identifier is a unique integer greater than zero.

    A message queue is created if either Fa key is equal to IPC_PRIVATE or Fa key does not have a message queue identifier associated with it, and the IPC_CREAT bit is set in Fa msgflg .

    If a new message queue is created, the data structure associated with it (the msqid_ds structure, see msgctl(3)) is initialized as follows:

     

    RETURN VALUES

    Upon successful completion a positive message queue identifier is returned. Otherwise, -1 is returned and the global variable errno is set to indicate the error.  

    ERRORS

    Bq Er EACCES
    A message queue is already associated with Fa key and the caller has no permission to access it.
    Bq Er EEXIST
    Both IPC_CREAT and IPC_EXCL are set in Fa msgflg , and a message queue is already associated with Fa key .
    Bq Er ENOSPC
    A new message queue could not be created because the system limit for the number of message queues has been reached.
    Bq Er ENOENT
    IPC_CREAT was not set in Fa msgflg and no message queue associated with Fa key was found.
