displaying #define values in C

Question

I have a series of #defines from a library file header of this sort:

typedef int Lib_error;   

#define   LIB_ERROR_A      ((Lib_error) 0x0000) 
#define   LIB_ER

Warning: The below code piece is just a sample. It can be improvised a lot which is for you to do. : )

Define a structure like below:

typedef struct ErrorStorage
{
  Lib_error err;
  char err_string[100];
}ErrNoStore;

ErrNoStore arrErr[25];

arrErr[0].err = LIB_ERROR_A;
strcpy(arrErr[0].err_string, "LIB_ERROR_A");
/... and so on .../

and later down in the code define a function like this and call it

void display_error(Lib_error errnum)
{
  int i = 0;

  for(i=0; i<25;i++)
  {
    if(errnum == arrErr[i].err)
    {
       printf("%s\n", arrErr[i].err_string);
    }
  }
}

}
