When system calls indicate an error they return -1, not some arbitrary

value < 0. errno is only updated in this case. Change all (most?) callers of syscalls to follow this better, and let's see if this strictness helps us in the future.

Add framework for resolving (pun intended) libc namespace issues, using

2015-08-31T02:53:56Z

wrapper .h files and asm labels to let internal calls resolve directly and not be overridable or use the PLT. Then, apply that framework to most of the functions in stdio.h, string.h, err.h, and wchar.h. Delete the should-have-been-hidden-all-along _v?(err|warn)[cx]? symbols while here. tests clean on i386, amd64, sparc64, powerpc, and mips64 naming feedback from kettenis@ and millert@ ok kettenis@

Add additional userland interfaces for setting close-on-exec on fds

2014-08-31T02:21:18Z

when creating them: mkostemp(), mkostemps(), the 'e' mode letter for fopen(), freopen(), fdopen(), and popen(). The close-on-exec flag will be cleared by the action created by posix_spawn_file_actions_adddup2(). Also, add support for the C11 'x' mode letter for fopen() and freopen(), setting O_EXCL when possibly creating files. Note: this requires kernel support for pipe2() and dup3()! ok millert@

make popen/pclose thread safe. closes library/5634. from and okay andreas@

zap remaining rcsid.

Kill old files that are no longer compiled. okay theo

deregister (and deauto!). ok millert@ marco@

in pclose(), only fclose() a stream if it has been opened by popen(), so

2004-08-06T18:31:11Z

that applications doing: 'ok = (pclose(f) != -1) || (fclose(f) == 0)' can work safely and avoid a double-close of a stream. ok millert@

ansify function definitions and zap some `register'
