silc_mutex_lock
SYNOPSIS
void silc_mutex_lock(SilcMutex mutex);
DESCRIPTION
Locks the mutex. If the mutex is locked by another thread the current thread will block until the other thread has issued silc_mutex_unlock for the mutex. If `mutex' is NULL this function has no effect.
NOTES
The caller must not call silc_mutex_lock for mutex that has been already locked in the current thread. In this case deadlock will occur.
