NAME
nn_term - terminate library (compatible API)
SYNOPSIS
#include <nanomsg/nn.h> void nn_term(void);
DESCRIPTION
The nn_term() function closes any open sockets, and frees all resources allocated by the library. Any operations that are currently in progress will be terminated, and will fail with error EBADF or ETERM.
Note
This function is provided for API
compatibility with legacy libnanomsg. Consider using the relevant
modern API instead.
Important
This function is not thread-safe, and is not suitable for use
in library calls. The intended purpose of this is to clean up at application
termination; for example by registering this function with
atexit(). This can help prevent false leak reports
caused when memory checkers notice global resources allocated by the
library. Libraries should never use this function, but should explicitly
close their own sockets directly.
RETURN VALUES
None.
ERRORS
None.
