Описание (Description)
This is a convenience function for extracting a captured
substring. 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
stringptr Where to put the string pointer
The memory in which the substring is placed is obtained by
calling pcre[16|32]_malloc(). The convenience function
pcre[16|32]_free_substring() can be used to free it when it is no
longer needed. The yield of the function is the length of the
substring, PCRE_ERROR_NOMEMORY if sufficient memory could not be
obtained, 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.
