1 .TH PCRE_COPY_SUBSTRING 3 "24 June 2012" "PCRE 8.30"
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);
22 .B int pcre32_copy_substring(PCRE_SPTR32 \fIsubject\fP, int *\fIovector\fP,
24 .B int \fIstringcount\fP, int \fIstringnumber\fP, PCRE_UCHAR32 *\fIbuffer\fP,
26 .B int \fIbuffersize\fP);
31 This is a convenience function for extracting a captured substring into a given
32 buffer. The arguments are:
34 \fIsubject\fP Subject that has been successfully matched
35 \fIovector\fP Offset vector that \fBpcre[16|32]_exec()\fP used
36 \fIstringcount\fP Value returned by \fBpcre[16|32]_exec()\fP
37 \fIstringnumber\fP Number of the required substring
38 \fIbuffer\fP Buffer to receive the string
39 \fIbuffersize\fP Size of buffer
41 The yield is the length of the string, PCRE_ERROR_NOMEMORY if the buffer was
42 too small, or PCRE_ERROR_NOSUBSTRING if the string number is invalid.
