NAME
qb_ipcc_verify_dgram_max_msg_size - Test kernel dgram socket buffers to verify the largest size up to the max_msg_size value a single msg can be.
SYNOPSIS
#include <qb/qbipcc.h>
int32_t
qb_ipcc_verify_dgram_max_msg_size
(
size_t
max_msg_size
/* biggest msg size. */
);
PARAMS
max_msg_size biggest msg size.
DESCRIPTION
Rounds down to the nearest 1k.
RETURN VALUE
-1 if max size can not be detected, positive value representing the largest single msg up to max_msg_size that can successfully be sent over a unix dgram socket.
