nn_reallocmsg − reallocate message (compatible API)
#include <nanomsg/nn.h>
void *nn_reallocmsg(void *old, size_t size);
The nn_reallocmsg() reallocates the message old, making it of size size.
Note
This function is provided for API compatibility with legacy libnanomsg. Consider using the relevant modern API instead.
On success, the contents of old are copied into the new message (truncating if appropriate), then old is deallocated, and a pointer to the new message payload is returned.
On failure, the old message is unchanged, and the value NULL is returned to the caller.
This function returns a pointer to message buffer space, or NULL on failure.
ENOMEM
Insufficient memory is available.
EINVAL
An invalid size was specified.
ETERM
The library is shutting down.
