#include <spawn.h>
int posix_spawnattr_getflags(const posix_spawnattr_t *restrict attr, short *restrict flags);
int posix_spawnattr_setflags(posix_spawnattr_t * attr, short flags);
The posix_spawnattr_getflags() function obtains the value of the spawn-flags attribute from the attributes object referenced by attr.
The posix_spawnattr_setflags() function sets the spawn-flags attribute in an initialized attributes object referenced by attr.
The spawn-flags attribute is used to indicate which process attributes are to be changed in the new process image when invoking posix_spawn(3C) or posix_spawnp(3C). It is the bitwise-inclusive OR of zero or more of the following flags:
POSIX_SPAWN_RESETIDS POSIX_SPAWN_SETPGROUP POSIX_SPAWN_SETSIGDEF POSIX_SPAWN_SETSIGMASK POSIX_SPAWN_SETSCHEDPARAM POSIX_SPAWN_SETSCHEDULER
These flags are defined in <spawn.h>. The default value of this attribute is as if no flags were set.
Upon successful completion, posix_spawnattr_getflags() returns 0 and stores the value of the spawn-flags attribute of attr into the object referenced by the flags parameter. Otherwise, an error number is returned to indicate the error.
Upon successful completion, posix_spawnattr_setflags() returns 0. Otherwise, an error number is returned to indicate the error.
These functions may fail if:
EINVAL The value specified by attr is invalid.
The posix_spawnattr_setflags() function may fail if:
EINVAL The value of the attribute being set is not valid.
