* NAME

|
* readv03.c
|
|
*
|
|
* DESCRIPTION
|
|
* Testcase to check the error condition of the readv(2) system call
|
|
* when fd refers to a directory.
|
|
*
|
|
* CALLS
|
|
* readv()
|
|
*
|
|
* ALGORITHM
|
|
* loop if that option was specified
|
|
* call readv() when fd refers to a directory.
|
|
* check the errno value
|
|
* issue a PASS message if we get EISDIR - errno 21
|
|
* otherwise, the tests fails
|
|
* issue a FAIL message
|
|
* call cleanup
