what do u mean by suspend?
sleep/block? if ur looking for a time-based threadsleep
maybe u can make use(improvise) with the select() function.
 
for example:

void threadSleep( int sec )
{
    struct timeval stTimeOut;
    int nSel;

    stTimeOut.tv_sec = sec;         /* Set the number of seconds       */
    stTimeOut.tv_usec = 0;          /* Set the number of micro seconds */

    nSel = select( 0, NULL, NULL, NULL, &stTimeOut);
}

what's wrong with using the pthread library? (ex: pthread_mutex_lock, 
pthread_mutex_unlock)
license issues? client-preference issues? library-comptability?
