dnl Provides a test to determine the correct way to call

|
dnl getservbyname_r:
|
|
dnl
|
|
dnl - defines HAVE_FUNC_GETSERVBYNAME_R_6 if it needs 6 arguments (e.g. linux)
|
|
dnl - defines HAVE_FUNC_GETSERVBYNAME_R_5 if it needs 5 arguments (e.g. solaris)
|
|
dnl - defines HAVE_FUNC_GETSERVBYNAME_R_4 if it needs 4 arguments (e.g. osf/1)

|
|
dnl An example use can be found at
|
|
dnl http://raf.org/autoconf/net_getservbyname.c
|
|
dnl
|
|
dnl Based on Caolan McNamara's gethostbyname_r macro. Based on David
