NAMEaa_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.
DESCRIPTIONThe 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 VALUEaa_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.
ERRORSaa_is_enabled ENOSYS AppArmor extensions to the system are not available. ECANCELED AppArmor is available on the system but has been disabled at boot. ENOENT AppArmor is available (and maybe even enforcing policy) but the interface is not available. ENOMEM Insufficient memory was available. EPERM Did not have sufficient permissions to determine if AppArmor is enabled. EACCES Did not have sufficient permissions to determine if AppArmor is enabled. aa_find_mountpoint ENOMEM Insufficient memory was available. EACCES Access to the required paths was denied. ENOENT The apparmor filesystem mount could not be found
