PCRE_STUDY(3) Library Functions Manual PCRE_STUDY(3) 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

PCRE_GET_STRINGTABLE_ENTRIES(3) Library Functions Manual PCRE_GET_STRINGTABLE_ENTRIES(3) NAME
PCRE - Perl-compatible regular expressions SYNOPSIS
#include <pcre.h> int pcre_get_stringtable_entries(const pcre *code, const char *name, char **first, char **last); DESCRIPTION
This convenience function finds, for a compiled pattern, the first and last entries for a given name in the table that translates capturing parenthesis names into numbers. When names are required to be unique (PCRE_DUPNAMES is not set), it is usually easier to use pcre_get_stringnumber() instead. code Compiled regular expression name Name whose entries required first Where to return a pointer to the first entry last Where to return a pointer to the last entry The yield of the function is the length of each entry, or PCRE_ERROR_NOSUBSTRING if none are found. There is a complete description of the PCRE native API, including the format of the table entries, in the pcreapi page, and a description of the POSIX API in the pcreposix page. ATTRIBUTES
