/* NAME

|
/* string_list 3
|
|
/* SUMMARY
|
|
/* match a string against a pattern list
|
|
/* SYNOPSIS
|
|
/* #include <string_list.h>
|
|
/*
|
|
/* STRING_LIST *string_list_init(pattern_list)
|
|
/* const char *pattern_list;
|
|
/*
|
|
/* int string_list_match(list, name)
|
|
/* STRING_LIST *list;
|
|
/* const char *name;
|
|
/*
|
|
/* void string_list_free(list)
|
|
/* STRING_LIST *list;
|
|
/* DESCRIPTION
|
|
/* This module implements tests for list membership of a string.
|
|
/*
|
|
/* 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 string matches a string list when it appears in the list of
|
|
/* string patterns. The matching process is case insensitive.
|
|
/* In order to reverse the result, precede a non-file name pattern
|
|
/* with an exclamation point (!).
|
|
/*
|
|
/* string_list_init() performs initializations. The argument is a
|
|
/* list of string patterns.
|
|
/*
|
|
/* string_list_match() matches the specified string against the
|
|
/* compiled pattern list.
|
|
/*
|
|
/* string_list_free() releases storage allocated by string_list_init().
|
|
/* DIAGNOSTICS
|
|
/* Fatal error: unable to open or read a pattern file or table.
|
|
