NAME

xs_msg_close - release Crossroads message

CONTENTS

SYNOPSIS

int xs_msg_close (xs_msg_t *msg);

DESCRIPTION

The xs_msg_close() function shall inform the Crossroads infrastructure that any resources associated with the message object referenced by msg are no longer required and may be released. Actual release of resources associated with the message object shall be postponed by the library until all users of the message or underlying data buffer have indicated it is no longer required.

Applications should ensure that xs_msg_close() is called once a message is no longer required, otherwise memory leaks may occur.

Caution

Never access xs_msg_t members directly, instead always use the xs_msg family of functions.

RETURN VALUE

The xs_msg_close() function shall return zero if successful. Otherwise it shall return -1 and set errno to one of the values defined below.

ERRORS

EFAULT

Invalid message.
