Create a link between a child process and a buffer, so that output from the child process is written to the buffer
the standard custom layer context pointer
the id of the child process who's output will be linked
the id of the buffer that will receive the output
flags setting the behavior when the child process or buffer already have a link
on success when the two entities exist and the link is created non-zero, otherwise zero
Each child process and each buffer may only be a part of one link at a time. So when either is already linked a decision needs to be made to either destroy that link or not create the new link. This decision is controlled by the flags.
