ShortToLossyFCB( string_t pFCBName, string_t p83Name, unsigned int length )
This service translates a unicode 8.3-format name into an FCB-format unicode name that is valid in the OEM namespace. Characters not valid in the OEM namespace are translated to underscores ('_'). This service is a variant of ShortToFCB and checks to see if a given unicode character can be converted into its corresponding BCS character in the current OEM codepage. ShortToFCB does not perform this check.
pFCBName
Supplies a flat pointer to the destination buffer to contain the FCB-format name. This buffer must be at least 22 bytes in length.
p83Name
Supplies a flat pointer to the source 8.3-format name.
length
Supplies the length in bytes of the source 8.3-format name.
