Fri Jul 30 07:48:05 CEST 2021
1) merge readv03 into readv02
2) use tst_get_bad_addr() API
3) use TST_EXP_FAIL2 macro

-/*
- * NAME
- * readv02.c
- *
+/*\
* DESCRIPTION
- * Testcase to check the error conditions of the readv(2) system call.
+ * test 1:
+ * The sum of the iov_len values overflows an ssize_t value, expect an EINVAL.
*
- * CALLS
- * readv()
+ * test 2:
+ * Buf is outside the accessible address space, expect an EFAULT.
*
- * ALGORITHM
- * Create a IO vector, and attempt to readv() various components of it.
+ * test 3:
+ * The vector count iovcnt is less than zero, expect an EINVAL.
*
- * USAGE
- * readv02
+ * test 4:
+ * The parameter passed to read is a directory, check if the errno is
+ * set to EISDIR.
*
- * HISTORY
- * 07/2001 Ported by Wayne Boyer
- *
- * RESTRICTIONS
- * None
+ * test 5:
+ * Read with an invalid file descriptor, and expect an EBADF.
