NAME¶

PCRE - Perl-compatible regular expressions

SYNOPSIS¶

#include <pcre.h> int pcre_copy_named_substring(const pcre *code, const char *subject, int * ovector, int stringcount, const char * stringname, char *buffer, int buffersize); int pcre16_copy_named_substring(const pcre16 *code, PCRE_SPTR16 subject, int *ovector, int stringcount, PCRE_SPTR16 stringname, PCRE_UCHAR16 *buffer, int buffersize);

DESCRIPTION¶

This is a convenience function for extracting a captured substring, identified by name, into a given buffer. The arguments are:
code Pattern that was successfully matched
subject Subject that has been successfully matched
ovector Offset vector that pcre[16]_exec() used
stringcount Value returned by pcre[16]_exec()
stringname Name of the required substring
buffer Buffer to receive the string
buffersize Size of buffer The yield is the length of the substring, PCRE_ERROR_NOMEMORY if the buffer was too small, or PCRE_ERROR_NOSUBSTRING if the string name 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.
