It's not clear (to me) what you are trying to do here: why can you not use fflush to flush a buffer?
Some immediate observations, though:
getchar returns EOF if nothing is read, rather than a NULL pointer, so don't compare its return value to NULL.
Writing to stdin is unlikely to succeed -- check the return value of fputc.

Hi,
Program A: uses pipe()
I am able to read the stdout of PROGAM B (stdout got through system() command) into PROGRAM A using:

* parent
-> char line;
-> read(fd, line, 100);

tai64nlocal
tai64nlocal(8) System Manager's Manual tai64nlocal(8)
NAME
tai64nlocal - converts precise TAI64N timestamps to a human-readable format.
SYNOPSIS
tai64nlocal
DESCRIPTION
tai64nlocal reads lines from stdin. If a line does not begin with @, tai64nlocal writes it to stdout without change. If a line begins with
@, tai64nlocal looks for a timestamp after the @, in the format printed by tai64n(8), and writes the line to stdout with the timestamp con-
verted to local time in ISO format: YYYY-MM-DD HH:MM:SS.SSSSSSSSS.
For example, in the US/Pacific time zone, the input line
@4000000037c219bf2ef02e94 mark
should be printed as
1999-08-23 21:03:43.787492500 mark
Beware, however, that the current implementation of tai64nlocal relies on the UNIX localtime library routine to find the local time. Some
localtime implementations use a broken time scale that does not account for leap seconds. On systems that use the Olson tz library (with an
up-to-date leap-second table), you can fix this problem by setting your time zone to, e.g, right/US/Pacific instead of US/Pacific.
Beware also that most localtime implementations are not Y2038-compliant.
tai64nlocal does not allocate any memory after it starts, except possibly inside localtime.
EXIT CODES
tai64nlocal exits 0 when it sees end of input. It exits 111 without an error message if it has trouble reading stdin or writing stdout.
