What's the meaning for XPG4?
And XPG1 2 3?

TKS!

Hi,

X/Open Portability Guide:

Have a look at these pages for a further explanation.

XPG (X/Open Portability Guide) is a standard that defines the interfaces of the X/Open Common Application environment based on POSIX and C. Then XPG 1,2,3 and 4 are just the versions of the standard or document. Also ake a look at a previous thread that I had a link to an article about UNIX95 (which is basically XPG4 command set).
