ax_func_which_gethostbyname_r ¶

Synopsis ¶

AX_FUNC_WHICH_GETHOSTBYNAME_R

Description ¶

Determines which historical variant of the gethostbyname_r() call (taking three, five, or six arguments) is available on the system and defines one of the following macros accordingly:

  HAVE_FUNC_GETHOSTBYNAME_R_6
  HAVE_FUNC_GETHOSTBYNAME_R_5
  HAVE_FUNC_GETHOSTBYNAME_R_3

as well as

  HAVE_GETHOSTBYNAME_R

If used in conjunction with gethostname.c, the API demonstrated in test.c can be used regardless of which gethostbyname_r() is available. These example files can be found at http://www.csn.ul.ie/~caolan/publink/gethostbyname_r

based on David Arnold’s autoconf suggestion in the threads faq

Originally named "AC_caolan_FUNC_WHICH_GETHOSTBYNAME_R". Rewritten for Autoconf 2.5x, and updated for 2.68 by Daniel Richard G.
