Direct memory writing

[Alejandro Torrijo]

Is there any application which permits writing in a process memory area?

Thanks in advance,
Alex

What memory is that? Are you talking about a debugger that can use ttrace to write to a process space?

Or with shared memory, you can just attached and then just load/store that memory.

The first is slow. The second runs at hardware speeds.

I am asking about process space. I know that it can be done with "wdb" but I would like to know if it is possible to use another application (supported HP application preferred).

[A. Clay Stephenson]

In a word, "no". The "supported" way for a group of processes to alter one another's memory is via shared memory segments. Consider the security and safety issues involved with what you seem to want to do. It would help if you described what you are trying to do and why; it might then be possible to offer better suggestions.

There is no /proc tree so there is no easy access to the memory image of all processes.

So what is wrong with using wdb/gdb?

[Alejandro Torrijo]

There is no problem at all. We just wanted to know if is there any other application to do this, but we would tell them to continue using wdb.

Application other than a debugger??

Basically there is only gdb. You can use wdb, ddd? or eclipse to sit on top of gdb.
