Full Discussion: Using write() with integers in C
Top Forums Programming Using write() with integers in C Post 302165622 by jim mcnamara on Friday 8th of February 2008 10:05:48 AM

Code:
int i=13;
write(my_fd, &i, sizeof(i));

This stores the internal integer the way it is stored in memory inside the file.
To make it human readable, assuming 32 bit integers:
Code:
char tmp[12]={0x0};
int i=13;
sprintf(tmp,"%11d", i);
write(my_fd, tmp, sizeof(tmp));

This writes a nul terminated string to the disk.
