Lines Matching full:callout
19 PCRE provides a feature called "callout", which is a means of temporarily

29 For example, this pattern has two callout points:
43 Notice that there is a callout before and after each parenthesis and
45 an assertion, an automatic callout is inserted immediately before the
46 condition. Such a callout may also be inserted explicitly, for example:
107 the callout is never reached. However, with "abyd", though the result is still
108 no match, the callout is obeyed.

124 During matching, when PCRE reaches a callout point, the external function
