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  con-
       texts.
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.
