SYNOPSIS
#include <nng/nng.h>
int nng_ctx_close(nng_ctx ctx);
DESCRIPTION
The nng_ctx_close()
function closes the context ctx.
Messages that have been submitted for sending may be flushed or delivered,
depending upon the transport and the setting of the
NNG_OPT_LINGER
option.
Further attempts to use the context after this call returns will result
in NNG_ECLOSED
.
Threads waiting for operations on the context when this
call is executed may also return with an NNG_ECLOSED
result.
Closing the socket associated with ctx
(using nng_close() ) also closes this context.
|
RETURN VALUES
This function returns 0 on success, and non-zero otherwise.
ERRORS
NNG_ECLOSED
|
The context ctx is already closed or was never opened. |
