XLIB Programming Manual, Rel. 5, Third Edition

H.3 Changes from Release 3 to Release 4

We will begin by describing the new functions, and then we will describe the small existing interface changes.

H.3.1 New Routines

Because of the adoption of the ICCCM (Inter-Client Communication Conventions Manual) as an X Consortium standard, several Xlib structures had to be changed, and therefore, several of the R3 routines are now superceded by new routines. All R3 routines are still supported, but the superseded routines should not be used in new applications because they do not meet the current conventions. Table H-1 lists the old and new routines.
