Re: C functions in RPG

[Joel Cochran <jrc@xxxxxxxxxx>]

John,

First, make sure you have the 'QC2LE' binding directory in your H Specs.

h bnddir('QC2LE')

Second, you need to prototype the call to any of the functions, and be
sure to do so using the appropriate case because C is case sensitive.

<pseudo-code>
d atoi                         pr                   extproc('atoi')
d  parm                                           *  options(*string)
</psuedo-code>

Sorry, I don't have an actual example handy...
