10 * qemu_ram_mmap: mmap the specified file or device.
11 *
12 * Parameters:
13 * @fd: the file or the device to mmap
14 * @size: the number of bytes to be mmaped
15 * @align: if not zero, specify the alignment of the starting mapping address;
16 * otherwise, the alignment in use will be determined by QEMU.
17 * @shared: map has RAM_SHARED flag.
18 * @is_pmem: map has RAM_PMEM flag.
19 *
20 * Return:
21 * On success, return a pointer to the mapped area.
22 * On failure, return MAP_FAILED.
