prelude_msgbuf_new ()

int
prelude_msgbuf_new (prelude_msgbuf_t **msgbuf);

Create a new prelude_msgbuf_t object and store it into msgbuf . You can then write data to msgbuf using the prelude_msgbuf_set() function.

When the message buffer is full, the message will be flushed using the user provided callback.

prelude_msgbuf_destroy ()

void
prelude_msgbuf_destroy (prelude_msgbuf_t *msgbuf);

Destroy msgbuf , all data remaining will be flushed.

prelude_msgbuf_mark_end ()

void
prelude_msgbuf_mark_end (prelude_msgbuf_t *msgbuf);

This function should be called to tell the msgbuf subsystem that you finished writing your message.

prelude_msgbuf_set ()

int
prelude_msgbuf_set (prelude_msgbuf_t *msgbuf,
                    uint8_t tag,
                    uint32_t len,
                    const void *data);

prelude_msgbuf_set() append len bytes of data from the data buffer to the msgbuf object representing a message. The data is tagged with tag .

prelude_msgbuf_get_msg ()

prelude_msg_t *
prelude_msgbuf_get_msg (prelude_msgbuf_t *msgbuf);

prelude_msgbuf_set_callback ()

void
prelude_msgbuf_set_callback (prelude_msgbuf_t *msgbuf,
                             int (*send_msg) (prelude_msgbuf_t *msgbuf, prelude_msg_t *msg));

Associate an application specific callback to this msgbuf .

prelude_msgbuf_set_data ()

void
prelude_msgbuf_set_data (prelude_msgbuf_t *msgbuf,
                         void *data);

prelude_msgbuf_get_data ()

void *
prelude_msgbuf_get_data (prelude_msgbuf_t *msgbuf);

prelude_msgbuf_set_flags ()

void
prelude_msgbuf_set_flags (prelude_msgbuf_t *msgbuf,
                          prelude_msgbuf_flags_t flags);

prelude_msgbuf_get_flags ()

prelude_msgbuf_flags_t
prelude_msgbuf_get_flags (prelude_msgbuf_t *msgbuf);

prelude_msgbuf_t

typedef struct prelude_msgbuf prelude_msgbuf_t;

enum prelude_msgbuf_flags_t
