Documentation

Provides a test to determine the correct way to call getservbyname_r:

  • - defines HAVE_FUNC_GETSERVBYNAME_R_6 if it needs 6 arguments (e.g linux)

  • - defines HAVE_FUNC_GETSERVBYNAME_R_5 if it needs 5 arguments (e.g. solaris)

  • - defines HAVE_FUNC_GETSERVBYNAME_R_4 if it needs 4 arguments (e.g. osf/1)

An example use can be found at http://raf.org/autoconf/net_getservbyname.c

Based on Caolan McNamara's gethostbyname_r macro. Based on David Arnold's autoconf suggestion in the threads faq.
