Hello, I’m hoping someone can help me convert the following from QNX 6 back
to QNX 4.
I’m trying to reach the physical memory address to use as a DMA buffer for a
video capture card. In QNX 6, I’ve found the following code that works,
however, I’m not finding mem_offset64 or similar in QNX4.
typedef long off64_t;
paddr_t mphys(void * addr)
if (mem_offset64(addr, NOFD, 1, &offset, 0)==-1)
I’m hoping someone could convert the above for me, or gimmie some hints.
