I am having problems with read (2)

len = read(fd,Buffer, sizeof(Buffer)-1);
Buffer[len] = '\0';

I am yet to get read to return 1
is this my bug or linux?

Are you expecting read to return 1? According to the man page, read
will return either the number of bytes actually read, or -1 if there's
an error. Have you checked what "sizeof(Buffer)-1" evaluates to?

assert (1 != read(fd,Buffer, sizeof(Buffer)-1));

assert (1 != read(fd,Buffer, sizeof(Buffer)-1));

assert (1 != read(fd,Buffer, sizeof(Buffer)-1));
