Description

The function pushnew-to-process-property pushes value to the value of the property associated with indicator for the process process . It uses the function test to compare existing property values of process with value and does not push if one matches, in the same way as cl:pushnew .

The default value of test is #'eql .

If there is a property associated with indicator , the value of the property must be a list.

If process is not supplied or is nil , the current process (that is, the result of calling get-current-process) is used.

result is the new value of the process property.

The modification is done in a thread-safe way.
