A pattern 27 /* is either a string, a file name (in which case the contents 28 /* of the file are substituted for the file name) or a type:name 29 /* lookup table specification. 30 /* 31 /* A string matches a string list when it appears in the list of 32 /* string patterns. The matching process is case insensitive. 33 /* In order to reverse the result, precede a pattern with an 34 /* exclamation point (!). 35 /* 36 /* string_list_init() performs initializations. The first argument 37 /* is a bit-wise OR of zero or more of following: 38 /* .IP MATCH_FLAG_RETURN 39 /* Request that string_list_match() logs a warning and returns 40 /* zero with list->error set to a non-zero dictionary error 41 /* code, instead of raising a fatal error. 42 /* .PP 43 /* Specify MATCH_FLAG_NONE to request none of the above. 44 /* The second argument specifies a list of string patterns. 45 /* 46 /* string_list_match() matches the specified string against the 47 /* compiled pattern list. 48 /* 49 /* string_list_free() releases storage allocated by string_list_init(). 50 /* DIAGNOSTICS 51 /* Fatal error: unable to open or read a pattern file or table. 52 /* SEE ALSO 53 /* match_list(3) generic list matching 54 /* match_ops(3) match strings by name or by address 55 /* LICENSE 56 /* .ad 57 /* .fi 58 /* The Secure Mailer license must be distributed with this software. 59 /* AUTHOR(S) 60 /* Wietse Venema 61 /* IBM T.J.
