What is the appropriate way to read/write integers from/to a file with the same size as it is stored in 
memory, i.e. a long integer (32bit) would occupy 4 bytes in the file. I have reached a solution but it seems 
rather clumsy:

#include<stdio.h>
void main()
{
 FILE *fileh;
 unsigned long my_long=0x41424344;
 char *charpek;
 fileh = fopen("test.dat","wb");
 charpek= (char *) &my_long;
 fprintf(fileh,"%c%c%c%c",*charpek,*(charpek+1),*(charpek+2),*(charpek+3));
 fclose(fileh);
}
