Assuming we are talking about the "fmumble" library routines here, this
is simply not possible, unless the program to be "exec"ed is rewritten
to co-operate with the program which will "exec" it (by recognizing a
"flush pipe output" option on its command line, for example).

If "fflush(3)" isn't what you have in mind, then I haven't the foggiest
notion what this means.  A specific example would be helpful.

Sometimes I think the only universal in the computing field is the
