Assuming there is not a probelm with emacs.  presumably 
other programs work fine under the shell.

stdout is buffered, so this is only output when the buffer
is full.  What happens if you explicity flush the output by

printf("my output");
fflush(stdout);

> exit(0);

This would cause the file buffer to be flushed to the output.

Quite right. One of the most useful things about running a
shell under emacs is you can search through the program's
output

Does your program flush the output?  What happens if you run
it from a shell outside of emacs?

yes, but only after exiting the program.

all output is immediately visible.

a little example:
/* c-code */
printf("my output");
/* "my output" now visible in the shell */

/* ... other lines of nice code */

exit(0);
/* "my output" now visible in my emacs buffer */


its a little bit exhausting to switch always between a shell
and emacs. it interrupts my working flow.


thanks for your help!
