+
+.SH "DESCRIPTION"
+.B is_context_customizable
+.br
+This function checks whether the type of scon is in the /etc/selinux/SELINUXTYPE/context/customizable_types file. A customizable type is a file context type that
+administrators set on files, usually to allow certain domains to share the file content. restorecon and setfiles, by default, leave these context in place.
+
+
+.SH "RETURN VALUE"
+returns 1 if security context is customizable or 0 if it is not.
+returns -1 on error
