nng_dialer_id(3)
NAME
nng_dialer_id - return numeric dialer identifier
SYNOPSIS
DESCRIPTION
The nng_dialer_id() function returns a positive identifier for the dialer d,
if it is valid.
Otherwise it returns -1.
A dialer is considered valid if it was ever created with the
nng_dialer_create() or
nng_dial() functions.
Dialers that are allocated on the stack or statically should be
initialized with the macro
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.
