Lines starting with # are treated like comments and ignored.
p .Nm krb5_acl_match_string matches ACL format against a string.
p 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.
p l -tag -width "fXX" -offset indent t s Matches a string using .Xr strcmp 3 (case sensitive). t f Matches the string with .Xr fnmatch 3 . The .Fa flags argument (the last argument) passed to the fnmatch function is 0. t 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
p All unknown format specifiers cause an error. .Sh EXAMPLES d -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"); } free(s); .Ed .Sh SEE ALSO .Xr krb5 3
