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.
