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

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.

       None.

       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.

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

       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
