posix_spawnattr_getsigignore_np, posix_spawnattr_setsigignore_np - get and set spawn-sigignore attribute of spawn attributes object
#include <signal.h> #include <spawn.h> int posix_spawnattr_getsigignore_np( const posix_spawnattr_t *restrict attr, sigset_t *restrict sigignore); int posix_spawnattr_setsigignore_np( posix_spawnattr_t *restrict attr, const sigset_t *restrict sigignore);
The posix_spawnattr_getsigignore_np() function obtains the value of the spawn-sigignore attribute from the attributes object referenced by attr. The posix_spawnattr_setsigignore_np() function sets the spawn-sigignore attribute in an initialized attributes object referenced by attr. The spawn-sigignore attribute represents the set of signals to be forced to be ignored in the new process image (if POSIX_SPAWN_SET- SIGIGN_NP is set in the spawn-flags attribute) by a spawn operation. The default value of this attribute is an empty signal set.
Upon successful completion, posix_spawnattr_getsigignore_np() returns 0 and stores the value of the spawn-sigignore attribute of attr into the object referenced by the sigignore parameter. Otherwise, an error value is returned to indicate the error. Upon successful completion, posix_spawnattr_setsigignore_np() returns 0. Otherwise, an error value is returned to indicate the error.
These functions may fail if: EINVAL The value specified by attr is invalid. The posix_spawnattr_setsigignore_np() function may fail if: EINVAL The value of the attribute being set is not valid.

The POSIX_SPAWN_SETSIGIGN_NP flag and the posix_spawnattr_getsigignore_np() and posix_spawnattr_setsigignore_np() functions are non-porta- ble Solaris extensions to the posix_spawn(3C) and posix_spawnp() interfaces. SunOS 5.11 28 Oct 2008 posix_spawnattr_getsigignore_np(3C)
