flux_msg_encode(3)

SYNOPSIS

#include <flux/core.h>

int flux_msg_encode (const flux_msg_t *msg,
                     void **buf,
                     size_t *size);

flux_msg_t *flux_msg_decode (void *buf, size_t size);

Link with -lflux-core.

DESCRIPTION

flux_msg_encode() converts msg to a serialized representation, allocated internally and assigned to buf, number of bytes to size. The caller must release buf with free(3).

flux_msg_decode() performs the inverse, creating msg from buf and size. The caller must destroy msg with flux_msg_destroy().

RETURN VALUE

flux_msg_encode() returns 0 on success. On error, -1 is returned, and errno is set appropriately.

flux_msg_decode() the decoded message on success. On error, NULL is returned, and errno is set appropriately.

ERRORS

EINVAL

Some arguments were invalid.

ENOMEM

Out of memory.
