posix_spawnattr_getflags, posix_spawnattr_setflags - get and set spawn-flags attribute of spawn attributes object

#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

POSIX_SPAWN_NOSIGCHLD_NP

POSIX_SPAWN_WAITPID_NP

POSIX_SPAWN_NOEXECERR_NP

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 posix_spawnattr_setflags() function may fail if:

EINVAL
