https://community.hpe.com/t5/operating-system-hp-ux/using-message-queue-in-64bit-amp-32bit-programs/m-p/3514195#M701009 Hello!<BR /><BR />I have two programs. The first program (assembled in 64bit mode (+DA2.0W)) uses msgsnd() function. The second program (assembled in 32 bit mode) uses msgrcv() to read messages from program 1.<BR />Msgsnd() and msgrcv() use msgp structure that contain mtype field as address of receiver of the message. BUT mtype is LONG type (4 bytes in 32bitmode and 8 in 64bitmode). <BR />I have a problem when program assembled in 64bitmode tries to read messages that was sended by 32bitmode program and vice versa.<BR /><BR />Thanks for reading this message.<BR />Yuri Ermakov.
