NAME    [Toc]    [Back]

     mac_get_proc, mac_set_proc	 - get or set the MAC label of this process

SYNOPSIS    [Toc]    [Back]

     #include <sys/mac.h>

     mac_t mac_get_proc(void);
     int mac_set_proc(mac_t macp);

DESCRIPTION    [Toc]    [Back]

     mac_get_proc returns a mac_t, a pointer to	an allocated struct mac_label
     which is the MAC label for	this process.

     mac_set_proc sets the MAC label of	the process.  The MAC label is first
     checked for validity by mac_valid(3c).  The process must have
     CAP_MAC_RELABEL_SUBJ capability in	its effective set to change its	MAC
     label.

RETURN VALUES    [Toc]    [Back]

     mac_get_proc a mac_t if successful, NULL otherwise.  The storage should
     be	freed with a call to mac_free with the returned	pointer	as an argument
     when it is	no longer needed.

     mac_set_proc returns 0 if successful, -1 otherwise.
