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.

ERRORS
