I have compiled a new kernel (3.2.9) for centos 4/5/6 servers. There is an issue with the centos 4, 32 bit servers. The kernel changes the order in which the MAC address is determined and because of this the server network does not come up as the wrong MAC address are assigned. Even if we specify... (6 Replies)
POSIX_SPAWNATTR_SETSPECIALPORT_NP(3) BSD Library Functions Manual POSIX_SPAWNATTR_SETSPECIALPORT_NP(3)NAME
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 ref-
erenced 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 bit-
field 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.
