== NAME

nng_tcp_dialer_close - close TCP dialer

== SYNOPSIS

[source, c]
----
#include <nng/nng.h>
#include <nng/supplemental/tcp/tcp.h>

void nng_tcp_dialer_close(nng_tcp_dialer *d);
----

== DESCRIPTION

The `nng_tcp_dialer_close()` function closes the supplied TCP dialer _d_,
but does not free the underlying resources associated with it.

If any dial operations
(see `<<nng_tcp_dialer_dial.3tcp#,nng_tcp_dialer_dial()>>`) using _d_ are
in progress, they will be terminated with an `NNG_ECLOSED` error condition.

Furthermore any future accesses to the dialer _d_ will also result in
`NNG_ECLOSED`.

NOTE: This function does not release the memory for the dialer, so the
application should still free the memory using
`<<nng_tcp_dialer_free.3tcp#,nng_tcp_dialer_free(3tcp)>>`
once it is certain that nothing else is using it.

== RETURN VALUES

None.

== ERRORS

None.
