    SYNOPSIS

    
           #include <pcre.h>
    
           int pcre_exec(const pcre *code, const pcre_extra *extra,
                const char *subject, int length, int startoffset,
                int options, int *ovector, int ovecsize);
    
    
    

    DESCRIPTION

    
           This  function  matches  a  compiled regular expression against a given
           subject string, using a matching algorithm that is similar  to  Perl's.
           It returns offsets to captured substrings. Its arguments are:
    
             code         Points to the compiled pattern
             extra        Points to an associated pcre_extra structure,
                            or is NULL
             subject      Points to the subject string
             length       Length of the subject string, in bytes
             startoffset  Offset in bytes in the subject at which to
                            start matching
             options      Option bits
             ovector      Points to a vector of ints for result offsets
             ovecsize     Number of elements in the vector (a multiple of 3)
    
           The options are:
    
             PCRE_ANCHORED      Match only at the first position
             PCRE_BSR_ANYCRLF   \R matches only CR, LF, or CRLF
             PCRE_BSR_UNICODE   \R matches all Unicode line endings
             PCRE_NEWLINE_ANY   Recognize any Unicode newline sequence
             PCRE_NEWLINE_ANYCRLF  Recognize CR, LF, and CRLF as newline sequences
             PCRE_NEWLINE_CR    Set CR as the newline sequence
             PCRE_NEWLINE_CRLF  Set CRLF as the newline sequence
             PCRE_NEWLINE_LF    Set LF as the newline sequence
             PCRE_NOTBOL        Subject is not the beginning of a line
             PCRE_NOTEOL        Subject is not the end of a line
             PCRE_NOTEMPTY      An empty string is not a valid match
             PCRE_NO_UTF8_CHECK Do not check the subject for UTF-8
                                  validity (only relevant if PCRE_UTF8
                                  was set at compile time)
             PCRE_PARTIAL       Return PCRE_ERROR_PARTIAL for a partial match
    
           There are restrictions on what may appear in  a  pattern  when  partial
           matching is requested. For details, see the pcrepartial page.
    
           A pcre_extra structure contains the following fields:
    
             flags        Bits indicating which fields are set
             study_data   Opaque data from pcre_study()
             match_limit  Limit on internal resource use
             match_limit_recursion  Limit on internal recursion depth
