Compile and Link the Print Formatter

Use an editor to create an imports file named sample.imp. The file should contain the

following:

main

piogetvals

piogetopt

piomsgout

pioexit

piomode

piodatasent

piopgskip

statusfile

piocmdout

piogetstr

Use an editor to create an exports file named sample.exp. The file should contain the

following:

setup

Enter the following to compile and link the formatter:

cc –o sample –bI:sample.imp –bE:sample.exp sample.c
