[net.sources] program to print contents

dixon@ihuxa.UUCP (08/05/83)

Recently a program to print a table of contents of functions in a C
language program was submitted to net.sources. This program used the
function call "dup2()", apparently a Berkeley Unix feature. I use
BTL Unix 5.0 (aka System V). Will someone tell me what dup2() does?
Is there a BTL 5.0 eqivalent? Thank you in advance.
