nng_ctx_close(3)

NAME

nng_ctx_close - close context

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.

Note
 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.
