/*
- * Test Name: ftruncate03
- *
* Test Description:
* Verify that,
- * 1) ftruncate(2) returns -1 and sets errno to EINVAL if the specified
- * socket is invalid.
- * 2) ftruncate(2) returns -1 and sets errno to EINVAL if the specified
- * file descriptor has an attempt to write, when open for read only.
- * 3) ftruncate(2) returns -1 and sets errno to EBADF if the file descriptor
- * of the specified file is not valid.
- *
- * Expected Result:
- * ftruncate() should fail with return value -1 and set expected errno.
- *
- * HISTORY
- * 02/2002 Written by Jay Huie
- * 02/2002 Adapted for and included into the LTP by Robbie Williamson
- *
- * RESTRICTIONS:
- * This test should be run by 'non-super-user' only.
- *
+ * 1)ftruncate() fails with EINVAL if the file is a socket.
+ * 2)ftruncate() fails with EINVAL if the file descriptor opens with O_RDONLY.
+ * 3)ftruncate() fails with EBADF if the file descriptor is invalid.
