GetControlCharSubst()

static Int_t GetControlCharSubst ( Int_t  c, char  buf[4]  )

static

When displaying text in a widget, a backslashed escape sequence is substituted for control characters that occur in the text.

Given a control character, fill in a buffer with the replacement string that should be displayed.

The return value is the length of the substitute string, buf is filled with the substitute string; it is not '\0' terminated.

c – The control character to be replaced. buf – Buffer that gets replacement string. It only needs to be 4 characters long.
