NAME
nng_ctx_close - close context
SYNOPSIS
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.
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. |
