*
|
|
*Purpose:
|
|
* Converts wide string pointed to by nptr to binary.
|
|
* Overflow is not detected. Because of this, we can just use

* atol().
|
|
*
|
|
*Entry:
|
|
* nptr = ptr to wide string to convert
|
|
*
|
|
*Exit:
|
|
* return long value of the string
|
|
*
|
|
*Exceptions:
|
|
* None - overflow is not detected.
