PCRE - Perl-compatible regular expressions
Contents
Description
This is a convenience function for extracting a captured substring into a given buffer. The arguments
are:
subject Subject that has been successfully matched
ovector Offset vector that pcre[16|32]_exec() used
stringcount Value returned by pcre[16|32]_exec()stringnumber Number of the required substring
buffer Buffer to receive the string
buffersize Size of buffer
The yield is the length of the string, PCRE_ERROR_NOMEMORY if the buffer was too small, or
PCRE_ERROR_NOSUBSTRING if the string number is invalid.
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.
