* NAME
|
||||
* read01.c
|
||||
*
|
||||
* DESCRIPTION
|
||||
* Testcase to check if read returns the number of bytes read correctly.
|
||||
*
|
||||
* ALGORITHM
|
||||
* Create a file and write some bytes out to it.
|
||||
* Attempt to read more than written.
|
||||
* Check the return count, and the read buffer. The read buffer should be
|
||||
* same as the write buffer.
|
||||
*
|
||||
* USAGE: <for command-line>
|
||||
* read01 [-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.
