NAME
       selinux_file_context_cmp - Compare two SELinux security contexts excluding the 'user' com-
       ponent

SYNOPSIS
       #include <selinux/selinux.h>

       int selinux_file_context_cmp(const char * a,
              const char * b);

DESCRIPTION
       selinux_file_context_cmp() compares two context strings excluding the user component  with
       strcmp(3) as shown in the EXAMPLE section.

       This is useful as for most object contexts, the user component is not relevant.

RETURN VALUE
       The return values follow the strcmp(3) function, where:
              0  if they are equal.
              1  if a is greater than b
              -1 if a is less than b

ERRORS
       None.

NOTES
       The contexts being compared do not specifically need to be file contexts.

EXAMPLE
       If context a is:
              user_u:user_r:user_t:s0

       and context b is:
              root:user_r:user_t:s0

       then the actual strings compared are:
              :user_r:user_t:s0 and :user_r:user_t:s0

       Therefore they will match and selinux_file_context_cmp() will return zero.
