create_message
3
create_message
allocates and initializes message
#include <cds/msg_queue.h>
int create_message
void *data
int data_len
Description
Allocates message using cds_malloc and initializes
its content so it will be freed automaticaly. Pointer to the explicitly
allocated data is set to data and its length is set to
data_len. Message created by create_message
should be freed using message_free.
Unremoved messages created this way are freed automaticaly in
msg_queue_destroy using free_message.
Calling free_message to such message frees the
message and the data given by parameter data too, thus
they can NOT be freed by the caller!
Return value
Returns NULL on error, pointer to initialized message structure otherwise.
