CharLowerBuff
The CharLowerBuff
function converts uppercase characters in a buffer to lowercase characters. The
function converts the characters in place. The function supersedes the AnsiLowerBuff
function.
DWORD CharLowerBuff(
|
LPTSTR lpsz, |
// pointer to
buffer containing characters to process |
|
DWORD cchLength |
// number of bytes
or characters to process |
|
); |
|
Parameters
lpsz
Pointer to a
buffer containing one or more characters to process.
cchLength
Specifies the
size, in bytes (ANSI version) or characters (Unicode version), of the buffer
pointed to by lpsz.
The function
examines each character, and converts uppercase characters to lowercase
characters. The function examines the number of bytes or characters indicated
by cchLength, even if one or more characters are null characters.
Return Values
If the function
succeeds, the return value is the number of bytes (ANSI version) or characters
(Unicode version) processed.
For example,
if CharLowerBuff("Acme of Operating Systems", 10) succeeds,
the return value is 10.
Remarks
Windows
NT: To make the conversion, the
function uses the language driver for the current language selected by the user
at setup or by using the Control Panel. If no language has been selected,
Windows completes the conversion by using internal default mapping. The
conversion is made based on the code page associated with the process locale.
Windows
95: The function makes the conversion
based on the information associated with the user's default locale, which is
the locale selected by the user at setup or by using the Control Panel. Windows
95 does not have language drivers.
