BTW I should have clarified why I decided on another name than regexecn() (I had considered this even before reading Peff's proposed patch): the <n> in string functions suggest a limiting of NUL-terminated strings. In other words, if n = 100 and the provided pointer points to a NUL-terminated string of length 3, the *n function will treat it as a string of length 3. That is not what regexec_buf() does: it ignores the NUL. Hence the different name. Ciao, Dscho
