# protocol used by each vop call. The first column is the name of
|

|
|
# the variable, the remaining three columns are in, out and error
|

|
# respectively. The "in" column defines the lock state on input,

# the "out" column defines the state on succesful return, and the
|
|
|
|
# "error" column defines the locking state on error exit.
|

|
|
|
|
# The locking value can take the following values:

|
# L: locked.
