CPINFO

The CPINFO structure contains information about a code page.

struct _cpinfo { 
  UINT MaxCharSize; 
  BYTE DefaultChar[MAX_DEFAULTCHAR]; 
  BYTE LeadByte[MAX_LEADBYTES]; 
} CPINFO, *LPCPINFO; 

Members

MaxCharSize

Specifies the maximum length, in bytes, of a character in this code page.

DefaultChar

Specifies the default character used in translations into this code page. This character is used by the WideCharToMultiByte function if an explicit default character is not specified.

LeadByte

Specifies a fixed-length array of lead-byte ranges, where the number of lead-byte ranges is variable. If there are no lead bytes in this code page, then every element of the array is NULL. If there are lead bytes in this code page, a starting value and ending value is specified for each range. Ranges are inclusive. The maximum number of lead-byte ranges for any code page is five. The array uses two bytes to describe each range, with a double-byte null terminator after the last range.

Remarks

Lead bytes are unique to double-byte character sets (DBCS). A lead byte is the first byte of a 2-byte character in a DBCS. Lead bytes occupy a specific range of byte values.

Requirements

  Windows NT/2000: Requires Windows NT 3.1 or later.
  Windows 95/98: Requires Windows 95 or later.
  Header: Declared in Winnls.h; include Windows.h.
