SUN_LEN - not available (CrUn342)

Problem description

The SUN_LEN macro exists on Tru64 UNIX, but not on HP-UX.

SUN_LEN is a convenience macro for UNIX domain sockets that takes a pointer to an initialized sockaddr_un structure and returns the length of the structure, including the number of non-null bytes in the path name.

Solution description

Copy the SUN_LEN macro from the Tru64 UNIX <sys/un.h> header.

New behavior

#include <sys/un.h>
#include <string.h>
#ifndef SUN_LEN
#define SUN_LEN(su) \
   (sizeof(*(su)) - sizeof((su)->sun_path) + strlen((su)->sun_path))
#endif
