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 withstrcmp(3) as shown in theEXAMPLEsection.       This is useful as for most object contexts, the user component is       not relevant.

RETURN VALUE        top

       The return values follow thestrcmp(3) function, where:              0  if they are equal.              1  ifa is greater thanb              -1 ifa is less thanb

ERRORS        top

       None.

NOTES        top

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

EXAMPLE        top

       If contexta is:              user_u:user_r:user_t:s0       and contextb 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 andselinux_file_context_cmp() will       return zero.
