AdsGetTableCharType

Returns the character type of the table (ANSI or OEM).

Syntax

UNSIGNED32 AdsGetTableCharType(ADSHANDLE hTable, UNSIGNED16 *pusCharType);

Parameters

Parameter	Type	Description
`hTable`	`ADSHANDLE`	Handle of the table.
`pusCharType`	`UNSIGNED16*`	Output — character type constant (`ADS_ANSI` or `ADS_OEM`).

Return Value

AE_SUCCESS (0) on success.

Description

AdsGetTableCharType returns the character type of the table. In OpenADS, this always returns ADS_ANSI (1) because OpenADS exclusively uses ANSI character encoding.

The character type determines how character data is stored and compared in the table. Traditional dBASE/FoxPro tables used OEM character encoding, while modern applications typically use ANSI.

ADS_ANSI (1): ANSI character encoding (Windows code page)
ADS_OEM (2): OEM character encoding (DOS code page)

Note that OpenADS does not support OEM character type — all tables are treated as ANSI.

Example

ADSHANDLE hTable;
UNSIGNED16 usCharType;

AdsOpenTable(&hTable, "customers.dbf", NULL, NULL, ADS_ANSI, ADS_SHARED, 0, 0, NULL);

AdsGetTableCharType(hTable, &usCharType);
if (usCharType == ADS_ANSI)
    printf("Table uses ANSI character encoding\n");
else if (usCharType == ADS_OEM)
    printf("Table uses OEM character encoding\n");

AdsCloseTable(hTable);
