AA_FIND_MOUNTPOINT(2)              AppArmor              AA_FIND_MOUNTPOINT(2)


NAME
       aa_is_enabled - determine if apparmor is available

       aa_find_mountpoint - find where the apparmor interface filesystem is
       mounted

SYNOPSIS
       #include <sys/apparmor.h>

       int aa_is_enabled(void);

       int aa_find_mountpoint(char **mnt);

       Link with -lapparmor when compiling.

DESCRIPTION
       The aa_is_enabled function returns true (1) if apparmor is enabled.  If
       it isn't it sets the errno(3) to reflect the reason it is not enabled
       and returns 0.

       The aa_find_mountpoint function finds where the apparmor filesystem is
       mounted on the system, and returns a string containing the mount path.
       It is the caller's responsibility to free(3) the returned path.

RETURN VALUE
       aa_is_enabled On success 1 is returned. On error, 0 is returned, and
       errno(3) is set appropriately.

       aa_find_mountpoint On success zero is returned. On error, -1 is
       returned, and errno(3) is set appropriately.
