1 .TH PCRE_COPY_SUBSTRING 3
3 PCRE - Perl-compatible regular expressions
10 .B int pcre_copy_substring(const char *\fIsubject\fP, int *\fIovector\fP,
12 .B int \fIstringcount\fP, int \fIstringnumber\fP, char *\fIbuffer\fP,
14 .B int \fIbuffersize\fP);
16 .B int pcre16_copy_substring(PCRE_SPTR16 \fIsubject\fP, int *\fIovector\fP,
18 .B int \fIstringcount\fP, int \fIstringnumber\fP, PCRE_UCHAR16 *\fIbuffer\fP,
20 .B int \fIbuffersize\fP);
25 This is a convenience function for extracting a captured substring into a given
26 buffer. The arguments are:
28 \fIsubject\fP Subject that has been successfully matched
29 \fIovector\fP Offset vector that \fBpcre[16]_exec()\fP used
30 \fIstringcount\fP Value returned by \fBpcre[16]_exec()\fP
31 \fIstringnumber\fP Number of the required substring
32 \fIbuffer\fP Buffer to receive the string
33 \fIbuffersize\fP Size of buffer
35 The yield is the length of the string, PCRE_ERROR_NOMEMORY if the buffer was
36 too small, or PCRE_ERROR_NOSUBSTRING if the string number is invalid.
