POSIX_SPAWNATTR_INIT(3) Library Functions Manual POSIX_SPAWNATTR_INIT(3) NAME posix_spawnattr_init, posix_spawnattr_destroy - initialize and destroy spawn attributes object LIBRARY Standard C Library (libc, -lc) SYNOPSIS #include <spawn.h> int posix_spawnattr_init(posix_spawnattr_t * attr); int posix_spawnattr_destroy(posix_spawnattr_t * attr); DESCRIPTION The posix_spawnattr_init() function initializes a spawn attributes object attr with the default value for all of the individual attributes used by the implementation. Initializing an already initialized spawn attributes object may cause memory to be leaked. The posix_spawnattr_destroy() function destroys a spawn attributes object. A destroyed attr attributes object can be reinitialized using posix_spawnattr_init(). The object should not be used after it has been destroyed. A spawn attributes object is of type posix_spawnattr_t (defined in <spawn.h>) and is used to specify the inheritance of process attributes across a spawn operation. The resulting spawn attributes object (possibly modified by setting individual attribute values), is used to modify the behavior of posix_spawn() or posix_spawnp(). After a spawn attributes object has been used to spawn a process by a call to a posix_spawn() or posix_spawnp(), any function affecting the attributes object (including destruction) will not affect any process that has been spawned in this way. RETURN VALUES Upon successful completion, posix_spawnattr_init() and posix_spawnattr_destroy() return zero; otherwise, an error number is returned to indicate the error. ERRORS The posix_spawnattr_init() function will fail if: [ENOMEM] Insufficient memory exists to initialize the spawn file actions object. SEE ALSO posix_spawn(3), posix_spawnp(3) STANDARDS The posix_spawnattr_init() and posix_spawnattr_destroy() functions conform to IEEE Std 1003.1-2001 ("POSIX.1"). HISTORY The posix_spawnattr_init() and posix_spawnattr_destroy() functions first appeared in FreeBSD 8.0 and imported for NetBSD 6.0.
