CharToOemBuffW function (winuser.h)
Translates a specified number of characters in a string into the OEM-defined character set.
Syntax
BOOL CharToOemBuffW(
[in] LPCWSTR lpszSrc,
[out] LPSTR lpszDst,
[in] DWORD cchDstLength
);
Parameters
[in] lpszSrc
Type: LPCTSTR
The null-terminated string to be translated.
[out] lpszDst
Type: LPSTR
The buffer for the translated string. If the CharToOemBuff function is being used as an ANSI function, the string can be translated in place by setting the lpszDst parameter to the same address as the lpszSrc parameter. This cannot be done if CharToOemBuff is being used as a wide-character function.
[in] cchDstLength
Type: DWORD
The number of characters to translate in the string identified by the lpszSrc parameter.
Return value
Type: BOOL
The return value is always nonzero except when you pass the same address to lpszSrc and lpszDst in the wide-character version of the function. In this case the function returns zero and GetLastError returns ERROR_INVALID_ADDRESS.
Remarks
Unlike the CharToOem function, the CharToOemBuff function does not stop converting characters when it encounters a null character in the buffer pointed to by lpszSrc. The CharToOemBuff function converts all cchDstLength characters.
Note
The winuser.h header defines CharToOemBuff as an alias that automatically selects the ANSI or Unicode version of this function based on the definition of the UNICODE preprocessor constant. Mixing usage of the encoding-neutral alias with code that is not encoding-neutral can lead to mismatches that result in compilation or runtime errors.
