In +/* order to reverse the result, precede a pattern with an +/* exclamation point (!). +/* +/* A host matches a list when its name or address matches +/* a pattern, or when any of its parent domains matches a +/* pattern. The matching process is case insensitive. +/* +/* namadr_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_PARENT +/* The hostname pattern foo.com matches itself and any name below +/* the domain foo.com. If this flag is cleared, foo.com matches itself +/* only, and .foo.com matches any name below the domain foo.com. +/* .IP MATCH_FLAG_RETURN +/* Request that namadr_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. +/* +/* namadr_list_match() matches the specified host name and +/* address against the specified list of patterns. +/* +/* namadr_list_free() releases storage allocated by namadr_list_init(). +/* DIAGNOSTICS +/* Fatal errors: unable to open or read a pattern file; invalid +/* pattern.
