dumping structure in C

Josephus Ross · 03-26-2007, 05:13 AM

Hi all,

I have a structure and I don't know what it is made of. Could somebody tell me how to output/dump a structure to the screen in a command prompt environment using C.

use gdb,making sure you compile the program with the gcc -g switch.

Loads of howto's etc on the net for gdb.

You could write the structure to a file using fwrite(), then use od view the file.

If you can write code referencing the structure there likely is an include file somewhere on your system that contains the declaration. (Though, not guaranteed, since the implementor could hide the internals by only defining a pointer for everyone else to use.)
