Routine Description: 
 
    Loads a string resource from the resource file associated with a 
    specified module, copies the string into a buffer, and appends a 
    terminating null character. 
 
Arguments: 
 
    hinst   handle to the module containing the string resource 
    id      ID of the string to be loaded 
    pwstr   points to the buffer to receive the string 
    bufsize size of the buffer, in characters. 
 
Return Value: 
 
    Return value is the number of characters copied into the buffer, not 
    including the null-terminating character.
