Synopsis:

#include <posix_spawnattr.h>

int posix_spawnattr_setsigdefault(
       posix_spawnattr_t *_Restrict attrp,
       const sigset_t *_Restrict sigset_p);

Arguments:

attrp

A spawn 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.

Description:

The posix_spawnattr_setsigdefault() function sets the spawn-sigset_p attribute in an initialized attributes object referenced by attrp.

Returns:

Upon successful completion, posix_spawnattr_setsigdefault() returns zero; otherwise, an error number is returned to indicate the error (errno is set).

Errors:

For any invalid parameter.

EOK

Success.
