Revision 1.3, Thu Jan 4 20:57:29 2018 UTC (6 years, 2 months ago) by kamil
Add bunch of missing includes of namespace.h in libc The NetBSD Standard C Library uses internally some of its functions with a mangled symbol name, usually "_symbol". The internal functions shall not use the global (public) symbols. This change eliminates usage of the global changes of the following symbols: - strlcat -> _strlcat - sysconf -> __sysconf - closedir -> _closedir - fparseln -> _fparseln - kill -> _kill - mkstemp -> _mkstemp - reallocarr -> _reallocarr - strcasecmp -> _strcasecmp - strncasecmp -> _strncasecmp - strptime -> _strptime - strtok_r -> _strtok_r - sysctl -> _sysctl - dlopen -> __dlopen - dlclose -> __dlclose - dlsym -> __dlsym Sponsored by <The NetBSD Foundation> |
