DTWAIN Functions A-Z

This section lists the DTWAIN functions in alphabetical order.

ANSI/Unicode specific functions

Note that for all of the DTWAIN functions that handle strings (either your application passes a string, or DTWAIN returns a string), there are ANSI and Unicode specific versions of the function.

The string arguments are either LPTSTR (pointer to platform-dependent string), or LPCTSTR (pointer to constant platform-dependent string).  For the ANSI version of the function, the LPTSTR/LPCTSTR will be LPSTR and LPCSTR.  For the Unicode version, the LPTSTR/LPCSTR will be LPWSTR and LPCWSTR.

For example:

DTWAIN_GetErrorString has an LPTSTR as a parameter.  The ANSI version would be DTWAIN_GetErrorStringA, and the single parameter would be LPSTR.  The Unicode version would be DTWAIN_GetErrorStringW and the single parameter would be LPWSTR.

If a function has ANSI/Unicode specific versions, the following entry will be listed:

Character specific version

ANSI version:         SomeFunctionA

Unicode version: SomeFunctionW

where SomeFunctionA and SomeFunctionW are the ANSI and Unicode specific versions of the function SomeFunction.
