| dnl Check for socklen_t: historically on BSD it is an int, and in |
| dnl POSIX 1g it is a type of its own, but some platforms use different |
| dnl types for the argument to getsockopt, getpeername, etc. So we |
| dnl have to test to find something that will work. |
| |
| dnl Remove the AC_CHECK_TYPE - on HP-UX it would find a socklen_t, but the |
| dnl function prototypes for getsockopt et al will not actually use |
| dnl socklen_t args unless _XOPEN_SOURCE_EXTENDED is defined. so, the |
| dnl AC_CHECK_TYPE will find a socklen_t and think all is happiness and |
| dnl joy when you will really get warnings about mismatch types - type |
| dnl mismatches that would be possibly Bad (tm) in a 64-bit compile. |
| dnl raj 2005-05-11 this change may be redistributed at will |
| |
| dnl also, added "extern" to the "int getpeername" in an attempt to resolve |
| dnl an issue with this code under Solaris 2.9. this too may be |
| dnl redistributed at will |
