commit 2a973ab7f1a6f6cd9be1c7257fd7b5d331515eab
Author: Adhemerval Zanella <adhemerval.zanella@linaro.org>
Date: Wed Sep 12 10:30:46 2018 -0300
posix: Add internal symbols for posix_spawn interface
This patch adds internal hidden definition for mostly of the posix_spawn
function so it can be used internally on both popen and system
implementations.
Checked on x86_64-linux-gnu.
* include/spawn.h (__posix_spawn, posix_spawn_file_actions_addclose,
__posix_spawn_file_actions_adddup2, __posix_spawn_file_actions_destroy,
__posix_spawn_file_actions_init, __posix_spawnattr_init,
__posix_spawnattr_destroy, __posix_spawnattr_setflags,
__posix_spawnattr_setsigdefault, __posix_spawnattr_setsigmask): New
prototype.
* posix/spawn.c (__posix_spawn): Add libc_hidden_def.
* posix/spawn_faction_addclose.c
(__posix_spawn_file_actions_addclose): Add hidden definition.
* posix/spawn_faction_adddup2.c
(__posix_spawn_file_actions_adddup2): Likewise.
* posix/spawn_faction_destroy.c
(__posix_spawn_file_actions_destroy): Likewise.
* posix/spawn_faction_init.c (__posix_spawn_file_actions_init):
Likewise.
* posix/spawnattr_destroy.c (__posix_spawnattr_destroy): Likewise.
* posix/spawnattr_init.c (__posix_spawnattr_init): Likewise.
* posix/spawnattr_setdefault.c (__posix_spawnattr_setsigdefault):
Likewise.
* posix/spawnattr_setflags.c (__posix_spawnattr_setflags): Likewise.
* posix/spawnattr_setsigmask.c (__posix_spawnattr_setsigmask):
Likewise.
