Here is a possible alternate solution (I really haven't understood the problem very well - I may be completely off here)
Code:
#include<stdlib.h>
#include<string.h>

int main(argc,argv)
int argc;
char *argv[];
{
        unsigned int dev=111,inode=222;
        char docname[]="/tmp/test";
        char *keybuf;
        int s_docname,s_key;

        s_docname=strlen(docname);
        s_key=s_docname+(sizeof(unsigned)*2)+1;
        keybuf=(char*)malloc(s_key);
        if(!keybuf) {
                perror("error in malloc!");
                exit(-1);
        }
        sprintf(keybuf,"%s %u %u",docname,dev,inode);
        fprintf(stdout,"%s\n",keybuf);
        docname[0]=0;
        dev=0;
        inode=0;
        fprintf(stdout,"doc: %s, dev: %d, inode: %d\n",docname,dev,inode);
        sscanf(keybuf,"%s %u %u",docname,&dev,&inode);
        fprintf(stdout,"post sscanf\n");
        fprintf(stdout,"doc: %s, dev: %d, inode: %d\n",docname,dev,inode);
        exit(0);
}

matchpathcon_filespec_eval

matchpathcon_checkmatches(3)				     SELinux API documentation				      matchpathcon_checkmatches(3)

NAME

       matchpathcon_checkmatches,  matchpathcon_filespec_add, matchpathcon_filespec_destroy, matchpathcon_filespec_eval - check and report whether
       any specification index has no matches with any inode. Maintenance and statistics on inode associations.

SYNOPSIS

       #include <selinux/selinux.h>

       void matchpathcon_checkmatches(char *str);

       int matchpathcon_filespec_add(ino_t ino, int specind, const char *file);

       void matchpathcon_filespec_destroy(void);

       void matchpathcon_filespec_eval(void);

DESCRIPTION

       matchpathcon_checkmatches checks whether any specification has no matches and reports them.  The str argument is used as a prefix  for  any
       warning messages.

       matchpathcon_filespec_add maintains an association between an inode ino and a specification index specind, and checks whether a conflicting
       specification is already associated with the same inode (e.g. due to multiple hard links). If so, then it uses the latter of the two speci-
       fications based on their order in the file context configuration. Returns the specification index used or -1 on error.

       matchpathcon_filespec_destroy destroys any inode associations that have been added, e.g. to restart for a new filesystem.

       matchpathcon_filespec_eval displays statistics on the hash table usage for the inode associations.

RETURN VALUE

       Returns zero on success or -1 otherwise.
