This call obtains a collating sequence table (for characters hex 00H through FFH) that resides in the country information file. It is used by the SORT utility to sort text according to the collating sequence.

Syntax

DosGetCollate (Length, Country, MemoryBuffer, DataLength)

Parameters

;Length (USHORT) - input: Length, in bytes, of the data area (MemoryBuffer). A length value of 256 is sufficient. ;Country (PCOUNTRYCODE) - input: Address of the country information structure ;MemoryBuffer (PCHAR) - output: Address of the collating table. 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 (in the order that the data would appear). If the amount of returned data does not fill the memory area provided by the caller, the unaltered memory is set at 0. :The buffer format for the returned information is: Byte Description

 0    Sort weight of ASCII (0)
 1    Sort weight of ASCII (1)
 .
 .
 .

255 Sort weight of ASCII (255) ;DataLength (PUSHORT) - output : Address of the length, in bytes, of the collate table.

Returns

;rc (USHORT) - return:Return code descriptions are: *0 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 country-dependent information can be for the default country and current process code page or for a specific country and code page. For more information see DosSetCp.

Bindings

C

<PRE> typedef struct _COUNTRYCODE { /* ctryc */

USHORT country; /* country code */

USHORT codepage;              /* code page */

} COUNTRYCODE;

#define INCL_DOSNLS

USHORT rc = DosGetCollate(Length, Structure, MemoryBuffer, DataLength);

USHORT Length; /* Length of data area provided */ PCOUNTRYCODE Structure; /* Input data structure */ PCHAR MemoryBuffer; /* Collate table (returned) */ PUSHORT DataLength; /* Length of collate table (returned) */

USHORT rc; /* return code */ </PRE>

MASM

<PRE> COUNTRYCODE struc

ctryc_country   dw  ? ;country code
ctryc_codepage  dw  ? ;code page

COUNTRYCODE ends

EXTRN DosGetCollate:FAR INCL_DOSNLS EQU 1

PUSH WORD Length ;Length of data area provided PUSH@ OTHER Structure ;Input data structure PUSH@ OTHER MemoryBuffer ;Collate table (returned) PUSH@ WORD DataLength ;Length of collate table (returned) CALL DosGetCollate

Returns WORD </PRE>

Example

This example gets a collating sequence table for codepage 850 and the current country. <PRE> #define INCL_DOSNLS #define CURRENT_COUNTRY 0 #define NLS_CODEPAGE 850

COUNTRYCODE Country; CHAR CollBuffer[256]; USHORT Length; USHORT rc;

Country.country = CURRENT_COUNTRY; Country.codepage = NLS_CODEPAGE;

rc = DosGetCollate(sizeof(CollBuffer), /* Length of data area provided */

                  &Country,           /* Input data structure */
                  CollBuffer,         /* Data area to contain collate table */
                  &Length);           /* Length of table */

</PRE>
