AreFileApisANSI function (fileapi.h)

Determines whether the file I/O functions are using the ANSI or OEM character set code page. This function is useful for 8-bit console input and output operations.

Syntax

BOOL AreFileApisANSI();

Return value

If the set of file I/O functions is using the ANSI code page, the return value is nonzero.

If the set of file I/O functions is using the OEM code page, the return value is zero.

Remarks

The SetFileApisToOEM function causes a set of file I/O functions to use the OEM code page. The SetFileApisToANSI function causes the same set of file I/O functions to use the ANSI code page. Use the AreFileApisANSI function to determine which code page the set of file I/O functions is currently using. For a discussion of these functions' usage, please see the Remarks sections of SetFileApisToOEM and SetFileApisToANSI.

The file I/O functions whose code page is ascertained by AreFileApisANSI are those functions exported by KERNEL32.DLL that accept or return a file name.

The functions SetFileApisToOEM and SetFileApisToANSI set the code page for a process, so AreFileApisANSI returns a value indicating the code page of an entire process.

In Windows 8 and Windows Server 2012, this function is supported by the following technologies.
