Re: getwd not available

Thanx for looking that up. I'll change it to 255.

@Scott ... and look how getwd is used just to be safe.

Thanx all.

Michael,

You have to be careful with PATH_MAX under IBM i. Although fully posix 
compliant functions may allow PATH_MAX of 1024, not all of the c 
functions do.

 From stdio.h
#ifndef PATH_MAX
   #ifndef __IFS_IO__
     #define PATH_MAX 39
   #else
     #define PATH_MAX 255
   #endif
#endif

See specific documentation for getconf()
http://publib.boulder.ibm.com/infocenter/iseries/v6r1m0/topic/rzahz/rzahzgetconf.htm
and pathconf()
http://publib.boulder.ibm.com/infocenter/iseries/v6r1m0/topic/apis/pathconf.htm
