Hi,
If I have an unsigned long int, instead printing out its values
in string using printf(%ld\n, my_var),
I would like to print it out as a 4-byte binary data. Is there
any easy way to do this in C.
Thanks.
Shao.

But isn't %[Xx] just prints out as Hexdecimal?
I just tried, and it prints out something like: 38c9616e
which consumes 8 bytes in a file. Given that unsigned long is 32 bits,
I want to use exactly 4 byte to represent it in order to save some
space.
Thanks.
Shao.

Sorry... I automatically made a link between binary data and hexadecimal
data...
You could shift 8 bits of the unsigned long into a unsigned char one at
a time, and print that character with a %c in the printf, or use
putchar() or something.
eg:
unsigned long l = 0x38c9616e;
You could just do:
fflush (stdout); /* clear the stream buffer */
write (1, myvar, 4); /* write binary to stdout */

Thanks. This is exactly what I want. I have thought about doing it this
way, it is just that from memory, there is a libc function that does the
equivalent.

What was given is the only safe and sane way I have ever seen. Bigger question
is why do you have a
