19     .SH DESCRIPTION
20     .rs
21     .sp
22     This function compiles a regular expression into an internal form. It is the
23     same as \fBpcre_compile()\fP, except for the addition of the \fIerrorcodeptr\fP
24     argument. The arguments are:
25    
26     .sp
27     \fIpattern\fR A zero-terminated string containing the
28     regular expression to be compiled
29     \fIoptions\fR Zero or more option bits
30     \fIerrorcodeptr\fP Where to put an error code
31     \fIerrptr\fR Where to put an error message
32     \fIerroffset\fR Offset in pattern where error was found
33     \fItableptr\fR Pointer to character tables, or NULL to
34     use the built-in default
35     .sp
36     The option bits are:
37     .sp
38     PCRE_ANCHORED Force pattern anchoring
39     PCRE_AUTO_CALLOUT Compile automatic callouts
40     PCRE_CASELESS Do caseless matching
41     PCRE_DOLLAR_ENDONLY $ not to match newline at end
42     PCRE_DOTALL . matches anything including NL
43     PCRE_EXTENDED Ignore whitespace and # comments
44     PCRE_EXTRA PCRE extra features
45     (not much use currently)
46     PCRE_FIRSTLINE Force matching to be before newline
47     PCRE_MULTILINE ^ and $ match newlines within data
48     PCRE_NO_AUTO_CAPTURE Disable numbered capturing paren-
49     theses (named ones available)
50     PCRE_UNGREEDY Invert greediness of quantifiers
51     PCRE_UTF8 Run in UTF-8 mode
52     PCRE_NO_UTF8_CHECK Do not check the pattern for UTF-8
53     validity (only relevant if
54     PCRE_UTF8 is set)
55     .sp
56     PCRE must be built with UTF-8 support in order to use PCRE_UTF8 and
57     PCRE_NO_UTF8_CHECK.
58     .P
59     The yield of the function is a pointer to a private data structure that
60     contains the compiled pattern, or NULL if an error was detected.
61     .P
62     There is a complete description of the PCRE native API in the
63     .\" HREF
64     \fBpcreapi\fR
65     .\"
66     page and a description of the POSIX API in the
67     .\" HREF
68     \fBpcreposix\fR
