Is there an equivalent to the perl command chomp in C? And if
there is no exact equivalent command, how would I go about
removing the "\n" at the end of a stdin?

int flushln(FILE *f) {
int ch;

while (('\n' != (ch = getc(f))) && (EOF != ch)) continue;
return ch;
}

That's a useful function, but it's doesn't bear any particular
resemblance to Perl's chomp function.

Probably so, but I suspect it is the answer to the OPs real
question, which was not well defined.

If you happen to know what Perl's chomp function does (which is
admittedly off-topic), the question is perfectly well defined, though
it could have been worded a bit better. The OP wants to remove a
trailing '\n' from a string (for example, from a string representing a
line read by fgets(). There's no indication that he wanted to discard
a line of input.

Anyway, in answer to the question

void
chomp(char *x) {
char *p = strrchr(x,'\n');
if(p) *p = 0;
}
.
