It was generated automatically from the original man page. If there is any nonsense in it, please consult the man page, in case the conversion went wrong. <br> <br><b> SYNOPSIS </b><br> <P> <b>#include <pcre.h></b> </P> <P> <b>int pcre_get_substring(const char *<i>subject</i>, int *<i>ovector</i>,</b> <b> int <i>stringcount</i>, int <i>stringnumber</i>,</b> <b> const char **<i>stringptr</i>);</b> <br> <br> <b>int pcre16_get_substring(PCRE_SPTR16 <i>subject</i>, int *<i>ovector</i>,</b> <b> int <i>stringcount</i>, int <i>stringnumber</i>,</b> <b> PCRE_SPTR16 *<i>stringptr</i>);</b> <br> <br> <b>int pcre32_get_substring(PCRE_SPTR32 <i>subject</i>, int *<i>ovector</i>,</b> <b> int <i>stringcount</i>, int <i>stringnumber</i>,</b> <b> PCRE_SPTR32 *<i>stringptr</i>);</b> </P> <br><b> DESCRIPTION </b><br> <P> This is a convenience function for extracting a captured substring. The arguments are: <pre> <i>subject</i> Subject that has been successfully matched <i>ovector</i> Offset vector that <b>pcre[16|32]_exec()</b> used <i>stringcount</i> Value returned by <b>pcre[16|32]_exec()</b> <i>stringnumber</i> Number of the required substring <i>stringptr</i> Where to put the string pointer </pre> The memory in which the substring is placed is obtained by calling <b>pcre[16|32]_malloc()</b>. The convenience function <b>pcre[16|32]_free_substring()</b> 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. </P> <P> There is a complete description of the PCRE native API in the <a href="pcreapi.html"><b>pcreapi</b></a> page and a description of the POSIX API in the <a href="pcreposix.html"><b>pcreposix</b></a> page. <p> Return to the <a href="index.html">PCRE index page</a>. </p>
