NAME¶
nng_dialer_id - return numeric dialer identifier
SYNOPSIS¶
#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
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.
