# DESCRIPTION:
|
|
# Tests file offset using O_APPEND.
|
|
#
|
|
# STRATEGY:
|
|
# 1. Open file using O_APPEND
|
|
# 2. Write to the file using random number of blocks (1, 2, or 3)
|
|
# 3. Verify that the file offset is correct using lseek after the write
|
|
# 4. Repeat steps 2 and 3, 5 times
|
|
# 5. Close the file.
|
|
# 6. Repeat steps 1-5 but also open file with O_DIRECT
|
|
#
