(String path, int mode) |
yoix.system |
| |
Checks whether the local file named by
path,
which can also begin with the
file:
prefix, can be accessed according to
mode,
and returns
0
on success or
-1
if there was an error.
mode
should be zero (or
F_OK),
which means check for the existence of the file, or an integer produced
by a bitwise-ORing of the constants
R_OK,
W_OK,
and
X_OK,
which are defined in
yoix.system.
The ability to test whether a file is really executable or not first
appeared in Java 1.6 and in that case
access
will provide an accurate answer, otherwise the
X_OK
test is exactly the same as the
R_OK
test.

| Example: |
On a UNIX-like system the program,
import yoix.stdio.*;
import yoix.system.*;
String path = "/etc/passwd";
if (access(path, R_OK) == 0)
printf("%s is readable\n", path);
else printf("%s is not readable\n", path);
if (access(path, W_OK) == 0)
printf("%s is writable\n", path);
else printf("%s is not writable\n", path);
usually prints
/etc/passwd is readable
/etc/passwd is not writable
on standard output.
