61 .Nm krb5_acl_match_file
62 matches ACL format against each line in a file.
63 Lines starting with # are treated like comments and ignored.
65 .Nm krb5_acl_match_string
66 matches ACL format against a string.
68 The ACL format has three format specifiers: s, f, and r.
69 Each specifier will retrieve one argument from the variable arguments
70 for either matching or storing data.
71 The input string is split up using " " and "\et" as a delimiter; multiple
72 " " and "\et" in a row are considered to be the same.

80 Matches the string with
84 argument (the last argument) passed to the fnmatch function is 0.
86 Returns a copy of the string in the char ** passed in; the copy must be
