mac_is_present
MAC_IS_PRESENT(3) BSD Library Functions Manual MAC_IS_PRESENT(3)NAME
mac_is_present -- report whether the running system has MAC support
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <sys/mac.h>
int
mac_is_present(const char *policyname);
DESCRIPTION
The mac_is_present() function determines whether the currently-running kernel supports MAC for a given policy or not. If policyname is
non-NULL, the presence of the named policy (e.g. ``biba'', ``mls'', ``te'') is checked, otherwise the presence of any MAC policies at all is
checked.
RETURN VALUES
If the system supports the given MAC policy, the value 1 is returned. If the specified MAC policy is not supported, the value 0 is returned.
If an error occurs, the value -1 is returned.
ERRORS
[EINVAL] The value of policyname is not valid.
[ENOMEM] Insufficient memory was available to allocate internal storage.
