Exporting all function addresses from IDA

Question

I have a x86 executable opened in IDA. In the function window you can see a list of all functions with their starting address.

My goal is to programmatically export a list of all functions IDA found including the following informations:

• Their starting address
• Their instructions as a byte array

How would i do this?

Answer 1

idc

auto func,i;
func = NextFunction(0);
while ( func != BADADDR ) 
{
    Message("start = %08x size = %04x    " , func , GetFunctionAttr(func,FUNCATTR_END )-func);
    for (i=0; i<0x10;i++)
    {
        Message("%02x ", Byte(func+i));
    }
    Message("\n");
    func = NextFunction(func);
}
