CharLowerBuffA function (winuser.h)

Converts uppercase characters in a buffer to lowercase characters. The function converts the characters in place.

Syntax

DWORD CharLowerBuffA(
  [in, out] LPSTR lpsz,
  [in]      DWORD cchLength
);

Parameters

[in, out] lpsz

Type: LPTSTR

A buffer containing one or more characters to be processed.

[in] cchLength

Type: DWORD

The size, in characters, 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 characters indicated by cchLength, even if one or more characters are null characters.

Return value

Type: DWORD

The return value is the number of characters processed. For example, if CharLowerBuff("Acme of Operating Systems", 10) succeeds, the return value is 10.

Remarks

Note that CharLowerBuff always maps uppercase I to lowercase I ("i"), even when the current language is Turkish or Azerbaijani. If you need a function that is linguistically sensitive in this respect, call LCMapSting.

Conversion to Unicode in the ANSI version of the function is done with the system default locale in all cases.

Examples

For an example, see "Creating a Spell Dialog Box" in Using Combo Boxes.
