Interfacing C and UNIX in SunView?

[Jonathan I. Kamens]

  (Note the Followup-To, which *should* have been included with the original
article.  The article doesn't belong in comp.unix.wizards in any case.  Heck,
it shouldn't have even been posted to the net, considering that the original
poster could have found out the answers to his questions by typing "man -k
execute", or "man -k command", or by asking a more knowledgeable programmer at
his site (the best solution).)

  See the man pages in section 3 of the manual for the library functions
system() and execl().  For example, system("lpr -<printer> <file>"); will
execute the lpr command.
