NAME
PCRE - Perl-compatible regular expressions SYNOPSIS
#include <pcre.h> pcre_extra *pcre_study(const pcre *code, int options, const char **errptr); DESCRIPTION
This function studies a compiled pattern, to see if additional information can be extracted that might speed up matching. Its arguments are: code A compiled regular expression options Options for pcre_study() errptr Where to put an error message If the function succeeds, it returns a value that can be passed to pcre_exec() via its extra argument. If the function returns NULL, either it could not find any additional information, or there was an error. You can tell the difference by looking at the error value. It is NULL in first case. There are currently no options defined; the value of the second argument should always be zero. 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. ATTRIBUTES

NAME
PCRE - Perl-compatible regular expressions SYNOPSIS
#include <pcre.h> int pcre_get_named_substring(const pcre *code, const char *subject, int *ovector, int stringcount, const char *stringname, const char **stringptr); DESCRIPTION
This is a convenience function for extracting a captured substring by name. The arguments are: code Compiled pattern subject Subject that has been successfully matched ovector Offset vector that pcre_exec() used stringcount Value returned by pcre_exec() stringname Name of the required substring stringptr Where to put the string pointer The memory in which the substring is placed is obtained by calling pcre_malloc(). The convenience function pcre_free_substring() can be used to free it when it is no longer needed. The yield of the function is the length of the extracted substring, PCRE_ERROR_NOMEMORY if sufficient memory could not be obtained, 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. ATTRIBUTES
