Re: Get the structure values from a c file
I apologize for some syntax errors in my c file. I would like to correct
my mistakes and append some lines in the c file to make it clearer.

#define max (3)
#define max_data_size (9600*2*8)
typedef unsigned char u8;
typedef signed int u32;
int some_data[] =
{
-288, -153, 31, 24, 205, 110, 39, 88,
-281, 145, 35, 266, 63, -79, -103, -25,
53, 145, -114, -274, 46, 60, 220, 205
};
typedef struct A
{
u32 a;
u8 b;
}A;
typedef struct MainStruct
{
A var1;
u32 var2;
u32 var3[max];
u32 var4;
u32 var5[max];
}MainStruct;
void generate()
{
MainStruct myMain = {0};
myMain.var1.a = 1;
myMain.var1.b = 'a';
myMain.var2 = 3;
myMain.var3[0] = -3;
myMain.var3[1] = 6;
myMain.var3[2] = 18;
(void)memcpy((void *)myMain.var4,
(void *)some_data,
sizeof(some_data));
myMain.var5[0] = 1;
}

This is a work-problem. Given a c file as input, the customer wants me
to write a python script that will retrieve the values of myMain.
He wants those values converted to binary data and write it in a .bin
file. As a result, the size of the bin file is equal to the size of
myMain. The c file input content might change in the future like
different values assigned, added fields in the MainStruct, etc. Also I
am not permitted to change the c file.
About me, I'm a fresh graduate. I just started learning python a month
ago. I learned c in school, we had it for 2 years.
I'm using python 2.6. I'm running on Windows 7 64-bit OS.
What I did so far is parse the C source code.
But having a problem parsing the value of myMain.var4.
