posix_spawnattr_setspecialport_np posix_spawnattr_setexceptionports_np —
set special ports on a posix_spawnattr_t
SYNOPSIS
#include <spawn.h>
int
posix_spawnattr_setspecialport_np(posix_spawnattr_t *attr,
mach_port_t new_port, int which);
int
posix_spawnattr_setexceptionports_np(posix_spawnattr_t *attr,
exception_mask_t mask, mach_port_t new_port,
exception_behavior_t behavior, thread_state_flavor_t flavor);
IMPORTANT
These functions represent an Apple extension to posix_spawn(2) and
posix_spawnp(2), and as such should not be used by programs intending
their code to be portable to other platforms.
DESCRIPTION
The posix_spawnattr_setspecialport_np() function sets a new value for a
Mach special port into the value referenced by attr to the port refer‐
enced by new_port for a port value of which, as if the new process had
called task_set_special_port().
The posix_spawnattr_setexceptionports_np() function sets the Mach port to
new_port for a number of exception ports represented by the bitfield
mask, and sets the new default behavior and default flavor, as if the new
process had called task_set_exception_ports().
RETURN VALUES
On success, these functions return 0; on failure they return an error
number from <errno.h>.
ERRORS
These functions may fail if:
[EINVAL] The value specified by attr is invalid.
[EINVAL] The value of attr is invalid.
[ENOMEM] Insufficient resources exist to set the ports.
