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. + + +SEE ALSO +-------- +linkxs:xs_msg_init_data[3] +linkxs:xs_msg_init[3] +linkxs:xs_msg_close[3] +linkxs:xs_msg_data[3] +linkxs:xs_msg_size[3] +linkxs:xs[7] + + +AUTHORS +------- +The Crossroads documentation was written by Martin Sustrik +and Martin Lucina . -- cgit v1.2.3
