nng_stream_dialer_alloc(3str)

SYNOPSIS

#include <nng/nng.h>

int nng_stream_dialer_alloc(nng_stream_dialer **dp, const char *addr);

int nng_stream_dialer_alloc_url(nng_stream_dialer **dp, const nng_url *url);

DESCRIPTION

These functions allocates a dialer for byte streams. Dialers create nng_stream objects by initiating outgoing connections, via the nng_stream_dialer_dial() function.

The first form, nng_stream_dialer_alloc(), connects to the address specified by addr, which should be a string representing a URL.

The second form, nng_stream_dialer_alloc_url(), takes a pre-parsed or pre-constructed nng_url object to determine the remote address.

These functions may support different URL schemes, such as ipc://, tcp://, tls+tcp://, or ws://.

Both forms store the dialer in the location referenced by dp.

RETURN VALUES

These functions return 0 on success, and non-zero otherwise.

ERRORS

NNG_ENOMEM

Insufficient free memory exists.

NNG_ENOTSUP

The URL scheme is not supported by the implementation.

NNG_EADDRINVAL

The URL requested is invalid.
