/***

|
* _strncnt - Return char count of string

|
*
|
|
*Purpose:
|
|
* Used for mapping _mbsnbcnt and _mbsnccnt to an equivilent non-MBCS
|
|
* implementation when _MBCS is not defined. Returns the minimum of
|
|
* strlen and bcnt.
|
|
*
|
|
*Entry:
|
|
* const unsigned char *string = pointer to string
|
|
* unsigned int bcnt = number of bytes to scan
|
|
*
|
|
*Exit:
|
|
* Returns number of chars/bytes between string and bcnt.
|
|
*
|
|
* If the end of the string is encountered before bcnt chars were
|
|
* scanned, then the length of the string in chars is returned.

*Exceptions:
