== NAME
|

|
|
|
||
|
|
nn_term - terminate library (compatible API)
|
||
|
|
|
||
|
|
== SYNOPSIS
|
||
|
|
|
||
|
|
[source,c]
|
||
|
|
----
|
||
|
|
#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
|
||
|
|
xref:nng_compat.3compat.adoc[compatibility] with legacy _libnanomsg_.
|
||
|
|
Consider using the relevant xref:libnng.3.adoc[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.
