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 shall obtain the value of the spawn-flags attribute from the attributes object referenced by attr.
The posix_spawnattr_setflags() function shall set 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() or posix_spawnp(). 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 shall be as if no flags were set.
Upon successful completion, posix_spawnattr_getflags() shall return zero and store the value of the spawn-flags attribute of attr into the object referenced by the flags parameter; otherwise, an error number shall be returned to indicate the error.
Upon successful completion, posix_spawnattr_setflags() shall return zero; otherwise, an error number shall be returned to indicate the error.
