NAME         top

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

SYNOPSIS         top

       #include <selinux/selinux.h>

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

DESCRIPTION         top

       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         top

       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         top

       None.

NOTES         top

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

EXAMPLE         top

       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.
