SQLGetConfigMode Function

  • Artikkeli

Conformance
Version Introduced: ODBC 3.0

Summary
SQLGetConfigMode retrieves the configuration mode that indicates where the Odbc.ini entry listing DSN values is in the system information.

Syntax

  
BOOL SQLGetConfigMode(  
     UWORD *   pwConfigMode);

Arguments

pwConfigMode
[Output] Pointer to the buffer containing the configuration mode. (See "Comments.") The value in *pwConfigMode can be:

ODBC_USER_DSN

ODBC_SYSTEM_DSN

ODBC_BOTH_DSN

Returns

The function returns TRUE if it is successful, FALSE if it fails.

Diagnostics

When SQLGetConfigMode returns FALSE, an associated *pfErrorCode value can be obtained by calling SQLInstallerError. The following table lists the *pfErrorCode values that can be returned by SQLInstallerError and explains each one in the context of this function.

*pfErrorCode Error Description
ODBC_ERROR_OUT_OF_MEM Out of memory The installer could not perform the function because of a lack of memory.

Comments

This function is used to determine where the Odbc.ini entry listing DSN values is in the system information. If *pwConfigMode is ODBC_USER_DSN, the DSN is a User DSN and the function reads from the Odbc.ini entry in HKEY_CURRENT_USER. If it is ODBC_SYSTEM_DSN, the DSN is a System DSN and the function reads from the Odbc.ini entry in HKEY_LOCAL_MACHINE. If it is ODBC_BOTH_DSN, HKEY_CURRENT_USER is tried, and if it fails, HKEY_LOCAL_MACHINE is used.

By default, SQLGetConfigMode returns ODBC_BOTH_DSN. When a User DSN or a System DSN is created by a call to SQLConfigDataSource, the function sets the configuration mode to ODBC_USER_DSN or ODBC_SYSTEM_DSN to distinguish user and System DSNs while modifying a DSN. Prior to returning, SQLConfigDataSource resets the configuration mode to ODBC_BOTH_DSN.
