EditWordBreakProcEx

The EditWordBreakProcEx function is an application-defined callback function used with the EM_SETWORDBREAKPROCEX message. It determines the character index of the word break, or the character class and word break flags of the characters in the specified text. The EDITWORDBREAKPROCEX type defines a pointer to this callback function. EditWordBreakProcEx is a placeholder for the application-defined function name.

LONG EditWordBreakProcEx(
  char *pchText,  
  LONG cchText,   
  BYTE bCharSet,  
  INT code        
);

cchText

Number of characters in the buffer in the direction specified by code.

bCharSet

Character set of the text.

code

Wordbreak action to take. Can be one of the values described for the code parameter in the EM_FINDWORDBREAK message.

Return Values
