Get the spawn-sigset_p attribute of a spawn attributes object
#include <posix_spawnattr.h>
int posix_spawnattr_getsigdefault(
const posix_spawnattr_t *_Restrict attrp,
sigset_t *_Restrict sigset_p);
- attrp
- A spawn file attribute object.
- sigset_p
- The child process's set of defaulted signals if you specify POSIX_SPAWN_SETSIGDEF in the flags member. The set of signals to be forced to default signal handling in the new process image (if POSIX_SPAWN_SETSIGDEF is set in the spawn-flags attribute) by a spawn operation. The default value of this attribute is an empty signal set.
The posix_spawnattr_getsigdefault() function shall obtain the value of the spawn-sigset_p attribute from the attributes object referenced by attrp.
Upon successful completion, posix_spawnattr_getsigdefault() returns zero and stores the value of the spawn-sigset_p attribute of attrp into the object referenced by the sigset_p parameter; otherwise, an error number is returned to indicate the error (errno is set).
- EINVAL
- For any invalid parameter.
- EOK
- Success.
