/* NAME
|
|
/* domain_list 3
|
|
/* SUMMARY
|
|
/* match a host or domain name against a pattern list
|
|
/* SYNOPSIS
|
|
/* #include <domain_list.h>
|
|
/*
|
|
/* DOMAIN_LIST *domain_list_init(pattern_list)
|
|
/* const char *pattern_list;
|
|
/*
|
|
/* int domain_list_match(list, name)
|
|
/* DOMAIN_LIST *list;
|
|
/* const char *name;
|
|
/*
|
|
/* void domain_list_free(list)
|
|
/* DOMAIN_LIST *list;
|
|
/* DESCRIPTION
|
|
/* This module implements tests for list membership of a host or
|
|
/* domain name.
|
|
/*
|
|
/* Patterns are separated by whitespace and/or commas. A pattern
|
|
/* is either a string, a file name (in which case the contents
|
|
/* of the file are substituted for the file name) or a type:name
|
|
/* lookup table specification.
|
|
/*
|
|
/* A host name matches a domain list when its name appears in the
|
|
/* list of domain patterns, or when any of its parent domains appears
|
|
/* in the list of domain patterns. The matching process is case
|
|
/* insensitive. In order to reverse the result, precede a non-file
|
|
/* name pattern with an exclamation point (!).
|
|
/*
|
|
/* domain_list_init() performs initializations. The argument is a
|
|
/* list of domain patterns, or the name of a file containing domain
|
|
/* patterns.
|
|
/*
|
|
/* domain_list_match() matches the specified host or domain name
|
|
/* against the specified pattern list.
|
|
/*
|
|
/* domain_list_free() releases storage allocated by domain_list_init().
|
|
/* DIAGNOSTICS
|
|
/* Fatal error: unable to open or read a domain_list file; invalid
|
|
/* domain_list pattern.
|
