Module name: src
Changes by: guenther@cvs.openbsd.org 2014/08/30 20:21:18

Modified files:
include : stdlib.h
lib/libc/gen : popen.3 popen.c posix_spawn.c
posix_spawn_file_actions_addopen.3
lib/libc/stdio : Makefile.inc fdopen.c flags.c fopen.3 freopen.c
mktemp.3 mktemp.c

Log message:
Add additional userland interfaces for setting close-on-exec on fds
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()!
