[Q] f2c questions
Bob Smither
I am porting a program from MS Powerstation to Linux using the fine
f2c/gcc combination. Three items are giving me problems:
1. Is there a built-in function that specifies the number of command line
arguments? I know how to get around this, but wondered if there were a
cleaner way.
2. Are time and date functions available, analogous to the MS calls
gettim and getdat?
3. Is there a method to provide user interaction during program
execution? I would like to be able to change some program parameters
such as convergence criteria from the keyboard while the program is running.
Many Thanks!

Yes, there is. The best way to learn all that f2c can do (and what
it can't) is to look at f2c.ps, the docs of f2c. Unfortunatelly, f2c.ps
is *NOT* distributed with the Linux binaries of f2c. You can get f2c.ps
from:
research.att.com:/netlib/f2c/f2c.ps.Z
: 2. Are time and date functions available, analogous to the MS calls
: gettim and getdat?
I think you'll have to use the C library to do that. Do a
prompt% apropos time
and see what you get from section 3 of the man pages. It should be
easy to make use of these C functions.

What is wrong with READ and WRITE/PRINT?
: Many Thanks!
