/*
- * Test Name: ftruncate01
- *
* Test Description:
- * Verify that, ftruncate(2) succeeds to truncate a file to a specified
- * length if the file indicated by file descriptor opened for writing.
- *
- * Expected Result:
- * ftruncate(2) should return a value 0 and the length of the file after
- * truncation should be equal to the length it is truncated to.
- *
- * Algorithm:
- * Setup:
- * Setup signal handling.
- * Create temporary directory.
- * Pause for SIGUSR1 if option specified.
- *
- * Test:
- * Loop if the proper options are given.
- * Execute system call
- * Check return code, if system call failed (return=-1)
- * Log the errno and Issue a FAIL message.
- * Otherwise,
- * Verify the Functionality of system call
- * if successful,
- * Issue Functionality-Pass message.
- * Otherwise,
- * Issue Functionality-Fail message.
- * Cleanup:
- * Print errno log and/or timing stats if options given
- * Delete the temporary directory created.
- *
- * Usage: <for command-line>
- * ftruncate01 [-c n] [-f] [-i n] [-I x] [-P x] [-t]
- * where, -c n : Run n copies concurrently.
- * -f : Turn off functionality Testing.
- * -i n : Execute test n times.
- * -I x : Execute test for x seconds.
- * -P x : Pause for x seconds between iterations.
- * -t : Turn on syscall timing.
- *
- * HISTORY
- * 07/2001 Ported by Wayne Boyer
- *
- * RESTRICTIONS:
- * This test should be run by 'non-super-user' only.
- *
+ * Verify that, ftruncate() succeeds to truncate a file to a certain length,
+ * if the file previously is smaller than the truncated size, ftruncate()
+ * shall increase the size of the file.
