Personaly, I use fgets/fflush and I did not see any problem (memory leak, etc) so far...
Something like:
#define INPUTSIZE 4096
char input[INPUTSIZE];
while (fgets(input, sizeof(input), stdin)) {
if ((cp=strchr(input, '\n')) == NULL) {
fprintf(stderr, "filter: input too big: %s\n", input);
} else {
*cp = '\0';
}
...
fflush(stderr);
fflush(stdout);
}
Do you use any malloc or functions that malloc... and that would need a free?
