mq_setattr(3c)

mq_setattr(3C)           Standard C Library Functions           mq_setattr(3C)

NAME
       mq_setattr - set/get message queue attributes

SYNOPSIS
       #include <mqueue.h>

       int mq_setattr(mqd_t mqdes, const struct mq_attr *mqstat,
            struct mq_attr *omqstat);

DESCRIPTION
       The mq_setattr() function is used to set attributes associated with the
       open message queue description referenced by the message queue descrip‐
       tor specified by mqdes.


       The message queue attributes corresponding to the following members de‐
       fined  in  the  mq_attr  structure are set to the specified values upon
       successful completion of mq_setattr():

       mq_flags    The value of this member is either 0 or O_NONBLOCK.



       The values of mq_maxmsg, mq_msgsize,  and  mq_curmsgs  are  ignored  by
       mq_setattr().


       If omqstat is non-NULL, mq_setattr() stores, in the location referenced
       by omqstat, the previous message queue attributes and the current queue
       status.  These  values  are  the same as would be returned by a call to
       mq_getattr() at that point.

RETURN VALUES
       Upon successful completion, mq_setattr() returns 0 and  the  attributes
       of  the  message  queue will have been changed as specified. Otherwise,
       the message queue attributes are unchanged, and the function returns −1
       and sets errno to indicate the error.

ERRORS
       The mq_setattr() function will fail if:

       EBADF     The mqdes argument is not a valid message queue descriptor.


       ENOSYS    The mq_setattr() function is not supported by the system.
