This function matches a compiled regular expression against a given subject
|
||
|
|
string, and returns offsets to capturing subexpressions. Its arguments are:
|
||
|
|
|
||
|
|
\fIcode\fR Points to the compiled pattern
|
||
|
|
\fIextra\fR Points to an associated \fBpcre_extra\fR structure,
|
||
|
|
or is NULL
|
||
|
|
\fIsubject\fR Points to the subject string
|
||
|
|
\fIlength\fR Length of the subject string, in bytes
|
||
|
|
\fIstartoffset\fR Offset in bytes in the subject at which to
|
||
|
|
start matching
|
||
|
|
\fIoptions\fR Option bits
|
||
|
|
\fIovector\fR Points to a vector of ints for result offsets
|
||
|
|
\fIovecsize\fR Size of the vector (a multiple of 3)
|
||
|
|
|
||
|
|
The options are:
|
||
|
|
|
||
|
|
PCRE_ANCHORED Match only at the first position
|
||
|
|
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)
