This call obtains a DBCS (double byte character set) environmental vector that resides in the country information file.

Syntax

DosGetDBCSEv (Length, Country, MemoryBuffer)

Parameters

;Length (USHORT) - input : Length, in bytes, of the data area (MemoryBuffer). This value should be at least 10. ;Country (PCOUNTRYCODE) - input : Address of the country information structure: countrycode (USHORT)

Country code identifier. 0 is the default country code.

codepage (USHORT)

Code page identifier. 0 is the code page of the current process.

; MemoryBuffer (PCHAR) - output : Address of the country dependent information for the DBCS environmental vector. This memory area is provided by the caller. The size of the area is provided by the input parameter Length. If it is too small to hold all the available information, then as much information as possible is provided in the available space.

The format of the information returned in this buffer is: Word Description 1 First range definition for DBCS lead byte values

High byte Binary start value (inclusive) for range one
Low byte Binary stop value (inclusive) for range one.

2 Second range definition

High byte Binary start value for range two
Low byte Binary stop value for range two.

N Nth range definition

High byte Binary start value for Nth range
Low byte Binary stop value for Nth range.

N + 1 Two bytes of binary 0 terminate list.

For example:
DB 81H,9FH DB E0H,FCH
DB 00H,00H

Return

rc (USHORT) - return

Return code descriptions are: * NO_ERROR * 396 ERROR_NLS_NO_COUNTRY_FILE * 397 ERROR_NLS_OPEN_FAILED * 398 ERROR_NO_COUNTRY_OR_CODEPAGE * 399 ERROR_NLS_TABLE_TRUNCATED

Remarks

The returned DBCS environmental vector may be for the default country and current process code page or for a specific country and code page. For more information on code page see DosSetCp.
