2 | dnl | |
3 | dnl Provides a test to determine the correct way to call | |
4 | dnl getservbyname_r: | |
5 | dnl | |
6 | dnl - defines HAVE_FUNC_GETSERVBYNAME_R_6 if it needs 6 arguments (e.g. linux) | |
7 | dnl - defines HAVE_FUNC_GETSERVBYNAME_R_5 if it needs 5 arguments (e.g. solaris) | |
8 | dnl - defines HAVE_FUNC_GETSERVBYNAME_R_4 if it needs 4 arguments (e.g. osf/1) | |
