.SH NAME
aa_is_enabled \- determine if apparmor is available
.PP
aa_find_mountpoint \- find where the apparmor interface filesystem is mounted
.SH SYNOPSIS
.IX Header "SYNOPSIS"
\&\fB#include <sys/apparmor.h>\fR
.PP
\&\fBint aa_is_enabled(void);\fR
.PP
\&\fBint aa_find_mountpoint(char **mnt);\fR
.PP
Link with \fB\-lapparmor\fR when compiling.
.SH DESCRIPTION
.IX Header "DESCRIPTION"
The aa_is_enabled function returns true (1) if apparmor is enabled.
If it isn't it sets the \fBerrno\fR\|(3) to reflect the reason it is not
enabled and returns 0.
.PP
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 \fBfree\fR\|(3) the returned path.
.SH "RETURN VALUE"
.IX Header "RETURN VALUE"
\&\fBaa_is_enabled\fR
On success 1 is returned. On error, 0 is returned, and \fBerrno\fR\|(3) is set
appropriately.
.PP
\&\fBaa_find_mountpoint\fR
On success zero is returned. On error, \-1 is returned, and \fBerrno\fR\|(3) is set
appropriately.
