problem with fprintf()


When I compile a simple program like below -

#include <stdio.h>

int main()
  FILE *f = fopen("test","w");
	fputc(0, f);
	fprintf(f,"%c", 0);
	return 0;

fputc() writes the character 0 correctly, but not fprintf().
In fact, fprintf() doesnt write anything! This happens only
with character 0 - I checked few others and they were ok.
What could be the reason?

Such a problem usually takes a long time to debug, better to
mention it somewhere :-)

I am using ETRAX 100 board with devboard-R1_0_2 software release.
