For each input datum, the \fBddi_mem_rep_get8()\fR, \fBddi_mem_rep_get16()\fR, \fBddi_mem_rep_get32()\fR, and \fBddi_mem_rep_get64()\fR functions read 8 bits, 16 bits, 32 bits and 64 bits of data, respectively, from the device address, \fIdev_addr\fR. \fIdev_addr\fR and \fIhost_addr\fR must be aligned to the datum boundary described by the function. .sp .LP Each individual datum will automatically be translated to maintain a consistent view between the host and the device based on the encoded information in the data access handle. The translation may involve byte-swapping if the host and the device have incompatible endian characteristics. .sp .LP When the \fIflags\fR argument is set to \fBDDI_DEV_AUTOINCR\fR, these functions will treat the device address, \fIdev_addr\fR, as a memory buffer location on the device and increments its address on the next input datum. However, when the \fIflags\fR argument is set to \fBDDI_DEV_NO_AUTOINCR\fR, the same device address will be used for every datum access. For example, this flag may be useful when reading from a data register. .SH CONTEXT These functions can be called from user, kernel, or interrupt context. .SH ATTRIBUTES See \fBattributes\fR(5) for descriptions of the following attributes: .sp .sp .TS box; c | c l | l .
