atop(3abz)

atop3abz

Convert a string to a port number

Usage

#include <abz/atop.h>

int atop(in_port_t *port, const char *str);

Libraries

Abz Library (-labz), Debug Library (-ldebug)

Overview

The atop() function converts a string to a port number. The string may either be a service as specified in /etc/services or a port number.

The port number is stored in network byte order.

Return value

The atop() function returns 0 if successful or -1 if some error occurred. Check errno to see what error occurred.

Notes

None of the libabz routines are thread-safe. I'm not planning to change this either! For more information, please see http://threading.2038bug.com/

If the library was compiled without the GETSERVBYNAME flag, only port numbers may be specified.
