Using sscanf to read in the file, Help please!

[vnrabbit]

Hello all,

I have something like this:

typedef void COMMAND (void);

typedef struct
{
int ID;
int copies;
int period;
int InUse;
COMMAND *function;
} resource;


resource resourceTable[6] = {
{A, 5, 6, 0, ProcessA},
{B, 2, 10, 0, ProcessB},
{C, 1, 0, 3, NULL},
{D, 1, 2, 0, NULL},
{E, 1, 2, 0, NULL},
{F, 3, 4, 0, NULL},
};

enum
{
A = 0,
B,
C,
D,
E,
F
}sources

Now I have a different definition file called definition.h:

A 5 6
B 2 10
C 1 0
D 1 2
E 1 2
F 3 4


Now in Main(), I want to read in the resourceTable from definition.h and Use sscanf function. Would anyone please help me to do it? Thank you very much!

1) sscanf is for scanning other strings, not files. Use fscanf.

2) Don't call your files that contain data ".h" files. ".h" files are header files that are #include-ed. Call it something else.

3) Learn to use fscanf from the link provided, then if you get stuck, post your attempt and we'll help you out.

o.k. I will

#include<stdio.h>
#include "definition.h"

int main(void)
{
FILE *fp;
fscanf(fp, "%s %d %d",resourceTable.ID, copies, period);

///some code
return 0;
}

is that right?
I don't know how to pass the argument in the () of fscanf. Please help!
Thanks!

You need to open the file first,

typedef void COMMAND (void);

what the hell is that, typedef is used to give a data type an alias name eg typedef int bool. This is valid in C because C doesn't have a builtin data type of bool.

He's defining a function pointer and putting it as a member of his struct.......

But if he's going down that road, he's better of using C++
