.Sh DESCRIPTION
|
|
.Nm krb5_acl_match_file
|
|
matches ACL format against each line in a file.
|
|
Lines starting with # are treated like comments and ignored.
|
|
.Pp
|
|
.Nm krb5_acl_match_string
|
|
matches ACL format against a string.
|
|
.Pp
|
|
The ACL format has three format specifiers: s, f, and r.
|
|
Each specifier will retrieve one argument from the variable arguments
|
|
for either matching or storing data.
|
|
The input string is split up using " " and "\et" as a delimiter; multiple
|
|
" " and "\et" in a row are considered to be the same.
|
|
.Pp
|
|
.Bl -tag -width "fXX" -offset indent
|
|
.It s
|
|
Matches a string using
|
|
.Xr strcmp 3
|
|
(case sensitive).
|
|
.It f
|
|
Matches the string with
|
|
.Xr fnmatch 3 .
|
|
The
|
|
.Fa flags
|
|
argument (the last argument) passed to the fnmatch function is 0.
|
|
.It r
|
|
Returns a copy of the string in the char ** passed in; the copy must be
|
|
freed with
|
|
.Xr free 3 .
|
|
There is no need to
|
|
.Xr free 3
|
|
the string on error: the function will clean up and set the pointer to
|
|
.Dv NULL .
|
|
.El
|
|
.Pp
|
|
All unknown format specifiers cause an error.
|
|
.Sh EXAMPLES
|
|
.Bd -literal -offset indent
|
|
char *s;
|
|
|
|
ret = krb5_acl_match_string(context, "foo", "s", "foo");
|
|
if (ret)
|
|
krb5_errx(context, 1, "acl didn't match");
|
|
ret = krb5_acl_match_string(context, "foo foo baz/kaka",
|
|
"ss", "foo", &s, "foo/*");
|
|
if (ret) {
|
|
/* no need to free(s) on error */
|
|
assert(s == NULL);
|
|
krb5_errx(context, 1, "acl didn't match");
|
|
}

|
