NAME

       selinux_file_context_cmp  -  Compare  two  SELinux  security contexts excluding the 'user'
       component

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.
