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 pname +/* argument specifies error reporting context. The flags +/* argument is the bit-wise OR of zero or more of the following: +/* .IP MATCH_FLAG_RETURN +/* Request that addr_match_list_match() logs a warning and +/* returns zero with list->error set to a non-zero dictionary +/* error code, instead of raising a fatal error. +/* .PP +/* Specify MATCH_FLAG_NONE to request none of the above. +/* The last 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.
