.Dd $Mdocdate: August 14 2013 $ .Dt POSIX_SPAWNATTR_INIT 3 .Os .Sh NAME .Nm posix_spawnattr_init , .Nm posix_spawnattr_destroy .Nd create and destroy posix_spawn attributes object .Sh SYNOPSIS n spawn.h .Ft int .Fn posix_spawnattr_init "posix_spawnattr_t *attr" .Ft int .Fn posix_spawnattr_destroy "posix_spawnattr_t *attr" .Sh DESCRIPTION .Xr posix_spawn 3 attributes objects can be initialized by .Fn posix_spawnattr_init and destroyed by .Fn posix_spawnattr_destroy .
p Initialization fills an attributes object pointed by .Fa attr with the default values for all the attributes.
p Multiple initialization of the same object is undefined behavior and will lead to memory leaks.
p Similarly, objects should be passed to .Fn posix_spawnattr_destroy to reclaim memory. The object should not be re-used after destruction. It can however be initialized again with .Fn posix_spawnattr_init .
p An attributes object, possibly modified by .Fn posix_spawn_set* , is used to specify what process attributes will be passed across a spawn operation as implemented by .Fn posix_spawn or .Fn posix_spawnp .
p Attribute details are described in .Xr posix_spawnattr_setflags 3 .
p Modifying or destroying attributes object will not affect processes that have already been spawned. .Sh RETURN VALUES These function return 0 on successful completion. They may return .Er ENOMEM when running out of memory. .Sh SEE ALSO .Xr posix_spawn 3 .Sh STANDARDS Both functions conform to .St -p1003.1-2001 . .Sh AUTHORS .An Ed Schouten Aq Mt ed@FreeBSD.org
