No changes have been made to function names for queue manipulation between the OS/2 Version 1.3 and OS/2 Version 2.0 implementations.
The queueing functions for the 16-bit and 32-bit environments are virtually identical; the only difference is that the 32-bit API uses 0:32 addressing and may use element sizes greater than 64KB. Note that a a 32-bit application may not open a queue created by a 16-bit application using the 16-bit DosCreateQueue() function.
