Re: IFS api openDir() const vs value -- RPG400-L

Hi,

Try to use the ifs function to open and read a directory.

Doc state the following:

DIR *opendir(const char *dirname)

However when we write the following PR it's not working

d openIFSDir Pr * ExtProc('opendir')

d * const options( *string )

Found the similar definition in Scott klements 'Working with the IFS in
RPG'
chapter.7

Instead of using the const he uses the value. But isn't telling why.

When running now I get a correct opendir result.

Is there someone who know the reason for this difference between the doc
and
the real world?

Best regards,

Danny
