explain_getaddrinfo_or_die − network address translation and report errors
#include <libexplain/getaddrinfo.h>
void explain_getaddrinfo_or_die(const char *node, const char *service, const struct addrinfo *hints, struct addrinfo **res);
The explain_getaddrinfo_or_die function is used to call the getaddrinfo(3) system call. On failure, an explanation will be printed to stderr, obtained from explain_getaddrinfo(3), and then the process terminates by calling exit(EXIT_FAILURE).
This function is intended to be used in a fashion similar to the following example:
explain_getaddrinfo_or_die(node, service, hints, res);
node |
The node, exactly as to be passed to the getaddrinfo(3) system call. |
||
service |
The service, exactly as to be passed to the getaddrinfo(3) system call. |
||
hints |
The hints, exactly as to be passed to the getaddrinfo(3) system call. |
||
res |
The res, exactly as to be passed to the getaddrinfo(3) system call. |
Returns:
This function only returns on success. On failure, prints an explanation and exits.
