NAME
nn_reallocmsg - reallocate message (compatible API)
SYNOPSIS
DESCRIPTION
The nn_reallocmsg() reallocates the message old, making it of size size.
| 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.
RETURN VALUES
This function returns a pointer to message buffer space, or NULL
on failure.
ERRORS
