/*++ /* NAME /* addr_match_list 3 /* SUMMARY /* address list membership /* SYNOPSIS /* #include <addr_match_list.h> /* /* ADDR_MATCH_LIST *addr_match_list_init(flags, pattern_list) /* int flags; /* const char *pattern_list; /* /* int addr_match_list_match(list, addr) /* ADDR_MATCH_LIST *list; /* const char *addr; /* /* void addr_match_list_free(list) /* ADDR_MATCH_LIST *list; /* DESCRIPTION /* This is a convenience wrapper around the match_list module. /* /* This module implements tests for list membership of a /* network address. /* /* A list pattern specifies an internet address, or a network/mask /* pattern, where the mask specifies the number of bits in the /* network part. When a pattern specifies a file name, its /* contents are substituted for the file name; when a pattern /* is a type:name table specification, table lookup is used /* instead. Patterns are separated by whitespace and/or commas. /* In order to reverse the result, precede a pattern with an /* exclamation point (!). /* /* A host matches a list when its address matches a pattern. /* The matching process is case insensitive. /* /* addr_match_list_init() performs initializations. The first /* argument is MATCH_FLAG_NONE for future extension. /* The second argument is a list of patterns, or the absolute /* pathname of a file with patterns. /* /* addr_match_list_match() matches the specified host address /* against the specified list of patterns. /* /* addr_match_list_free() releases storage allocated by /* addr_match_list_init(). /* DIAGNOSTICS /* Fatal errors: unable to open or read a pattern file; invalid /* pattern. Panic: interface violations. /* SEE ALSO /* match_list(3) generic list matching /* match_ops(3) match host by name or by address /* LICENSE /* .ad /* .fi /* The Secure Mailer license must be distributed with this software. /* AUTHOR(S) /* Wietse Venema /* IBM T.J.
