== NAME
|
|
|
|
nng_dialer_id - return numeric dialer identifier
|
|
|
|
== SYNOPSIS
|
|
|
|
[source, c]
|
|
----
|
|
#include <nng/nng.h>
|
|
|
|
int nng_dialer_id(nng_dialer d);
|
|
----
|
|
|
|
== DESCRIPTION
|
|
|
|
The `nng_dialer_id()` function returns a positive identifier for the dialer _d_,
|
|
if it is valid.
|
|
Otherwise it returns `-1`.
|
|
|
|
NOTE: A dialer is considered valid if it was ever created with the
|
|
xref:nng_dialer_create.3.adoc[`nng_dialer_create()`] or
|
|
xref:nng_dial.3.adoc[`nng_dial()`] functions.
|
|
Dialers that are allocated on the stack or statically should be
|
|
initialized with the macro
|
|
xref:nng_ctx.5.adoc#NNG_DIALER_INITIALIZER[`NNG_DIALER_INITIALIZER`] to ensure that
|
|
they cannot be confused with a valid dialer before they are created properly.
|
|
|
|
== RETURN VALUES
|
|
|
|
This function returns the positive value for the dialer identifier, or
|
|
`-1` if the dialer is invalid.
|
|
|
|
== ERRORS
|
|
|
|
None.
