|
||||
* Test Name: mmap06
|
||||
*
|
||||
* Test Description:
|
||||
* Call mmap() to map a file creating a mapped region with read access
|
||||
* under the following conditions -
|
||||
* - The prot parameter is set to PROT_READ
|
||||
* - The file descriptor is open for writing.
|
||||
*
|
||||
* The call should fail to map the file.
|
||||
*
|
||||
* Expected Result:
|
||||
* mmap() should fail returning -1 and errno should get set to EACCES.
|
||||
*
|
||||
* Algorithm:
|
||||
* Setup:
|
||||
* Setup signal handling.
|
||||
* Pause for SIGUSR1 if option specified.
|
||||
* Create temporary directory.
|
||||
*
|
||||
* Test:
|
||||
* Loop if the proper options are given.
|
||||
* Execute system call
|
||||
* Check return code, if system call failed (return=-1)
|
||||
* if errno set == expected errno
|
||||
* Issue sys call fails with expected return value and errno.
|
||||
* Otherwise,
|
||||
* Issue sys call fails with unexpected errno.
|
||||
* Otherwise,
|
||||
* Issue sys call returns unexpected value.
|
||||
*
|
||||
* Cleanup:
|
||||
* Print errno log and/or timing stats if options given
|
||||
* Delete the temporary directory(s)/file(s) created.
|
||||
*
|
||||
* Usage: <for command-line>
|
||||
* mmap06 [-c n] [-e] [-i n] [-I x] [-P x] [-t]
|
||||
* where, -c n : Run n copies concurrently.
|
||||
* -e : Turn on errno logging.
|
||||
* -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.
