NAME
PCRE - Perl-compatible regular expressions
SYNOPSIS
#include <pcre.h>
pcre *pcre_compile(const char *pattern, int options,
const char **errptr, int *erroffset,
const unsigned char *tableptr);
DESCRIPTION
This function compiles a regular expression into an internal form. Its arguments are: pattern A zero-terminated string containing the regular expression to be compiled options Zero or more option bits errptr Where to put an error message erroffset Offset in pattern where error was found tableptr Pointer to character tables, or NULL to use the built-in default The option bits are: PCRE_ANCHORED Force pattern anchoring PCRE_AUTO_CALLOUT Compile automatic callouts PCRE_CASELESS Do caseless matching PCRE_DOLLAR_ENDONLY $ not to match newline at end PCRE_DOTALL . matches anything including NL PCRE_EXTENDED Ignore whitespace and # comments PCRE_EXTRA PCRE extra features (not much use currently) PCRE_FIRSTLINE Force matching to be before newline PCRE_MULTILINE ^ and $ match newlines within data PCRE_NO_AUTO_CAPTURE Disable numbered capturing paren- theses (named ones available) PCRE_UNGREEDY Invert greediness of quantifiers PCRE_UTF8 Run in UTF-8 mode PCRE_NO_UTF8_CHECK Do not check the pattern for UTF-8 validity (only relevant if PCRE_UTF8 is set) PCRE must be built with UTF-8 support in order to use PCRE_UTF8 and PCRE_NO_UTF8_CHECK.
The yield of the function is a pointer to a private data structure that contains the compiled pattern, or NULL if an error was detected.
There is a complete description of the PCRE native API in the pcreapi page and a description of the POSIX API in the pcreposix page.
