Описание (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.
