CharUpperBuff function

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

Syntax


DWORD WINAPI CharUpperBuff(
  _Inout_  LPTSTR lpsz,
  _In_     DWORD cchLength
);

Parameters

lpsz [in, out]

Type: LPTSTR

A buffer containing one or more characters to be processed.

cchLength [in]

Type: DWORD

The size, in characters, of the buffer pointed to by lpsz.

The function examines each character, and converts lowercase characters to uppercase 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 CharUpperBuff("Zenith of API Sets", 10) succeeds, the return value is 10.

Remarks

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

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 and Using a Temporary File.
