SYNOPSIS
int xs_msg_init_size (xs_msg_t *msg, size_t size);
DESCRIPTION
The xs_msg_init_size() function shall allocate any resources required to store a message size bytes long and initialise the message object referenced by msg to represent the newly allocated message.
The implementation shall choose whether to store message content on the stack (small messages) or on the heap (large messages). For performance reasons xs_msg_init_size() shall not clear the message data.
-
Caution
Never access xs_msg_t members directly, instead always use the xs_msg family of functions.
-
Caution
The functions xs_msg_init(), xs_msg_init_data() and xs_msg_init_size() are mutually exclusive. Never initialize the same xs_msg_t twice.
RETURN VALUE
The xs_msg_init_size() function shall return zero if successful. Otherwise it shall return -1 and set errno to one of the values defined below.
ERRORS
ENOMEM
- Insufficient storage space is available.
