Well, C doesn't have any built-in "mail binary file" operator, so we'll
have to fudge it. It would probably be easier to use "system()" to
invoke mail, although using "popen()" might be more efficient.

#include <stdio.h>
int main() 
{
  FILE *binfile,*textfile;
  int c;

  binfile=fopen("fname.bin","r");
  textfile=fopen("fname.txt","w");

  fprintf(textfile,"---cut here---\n");
  while ((c=getc(binfile))!=EOF) {
    fprintf(textfile,"%#X ",c);
  }
  fclose(textfile);
  fclose(binfile);
  system("mail user@domain < fname.txt");
}

I would have, but seeing how this is just so applicable to comp.lang.c, I
thought I'd post it.
