Re: hooking the sept

["Leif Svalgaard" <leif@xxxxxxxx>]

2. the sept space can be duplicated?  by CrtDupObj? by creating a user space called MySept and using CPYBWP to copy the contents of Sept to MySept?

 

===> you don'r need a space. You can copy the SEPT (from x'1000' onwards)

with CPYBWP to a data-item in your program, then

set a pointer to the data-item in the PCO....

 

4. This pco spcptr is used as the base pointer for all subsequent access to the sept?

 

5. a job could use CPYBWP to change the spcptr in the pco to point to MySept instead of the real Sept?

 

6. you are then in mi heaven, able to intercept all sorts of system calls?

 

Thanks for the help,

Steve
