Hello friends,

again one silly question, how i can dump all the data members of task_struct structure into a file?? as the structure itself is very big and moreover its most of members are also pointers to other structure so what can be done in this case?? plz help me

thanx in advanvce,

If you are wanting to follow the pointers then you will need to write a function that will dump the details for you.

My previous answer is assuming that the program is in C or C++, many other languages come with constructs to help you with the particular problem you are describing. But the pointers in a structure led me down the C path. If I've inferred incorrectly then the above answer may also be incorrect

hello will u please give me any example that how i can write a structure into a file specially when it has got pointes to other structures??

Thankx in advance.

You will need to write the code specific to the structure. Essentially using printf()'s to print out the data and when you come to a pointer dereference the data before printing.

On complex structures you may want to write a function for each sub structure so that you just call the dump function for the sub structure, quite useful if the structure includes an array of pointers to the same sub structure.

You need to be careful if the structure might hold a circular reference.
