match found, and returns the new value of point.

+These are @dfn{non-greedy} variants of the operators @samp{*}, @samp{+}
and @samp{?}. Where those operators match the largest possible
substring (consistent with matching the entire containing expression),
the non-greedy variants match the smallest possible substring
This matches @samp{0} through @samp{9}. Thus, @samp{[-+[:digit:]]}
matches any digit, as well as @samp{+} and @samp{-}.
@item [:graph:]

+This matches graphic characters---everything except whitespace,

+surrogates, and codepoints unassigned by Unicode, as indicated by the
+Unicode @samp{general-category} property (@pxref{Character
+Properties}).
@item [:lower:]
This matches any lower-case letter, as determined by the current case
table (@pxref{Case Tables}). If @code{case-fold-search} is
@item [:nonascii:]
This matches any non-@acronym{ASCII} character.
@item [:print:]

+This matches any printing character---either whitespace, or a graphic
+character matched by @samp{[:graph:]}.
@item [:punct:]
This matches any punctuation character. (At present, for multibyte
characters, it matches anything that has non-word syntax.)
The index of the first character of the
string is 0, the index of the second character is 1, and so on.

+If the last regular expression search found a match, this function
+returns the position of the start of the matching text or of a

If @var{count} is zero, then the value is the position of the start of
