NAME
csxRepGet8, csxRepGet16, csxRepGet32, csxRepGet64 - read
repetitively from the device register
SYNOPSIS
#include
void csxRepGet8(acchandlet handle, uint8t *hostaddr, uint32t offset,
uint32t repcount, uint32t flags);
void csxRepGet16(acchandlet handle, uint16t *hostaddr, uint32t offset,
uint32t repcount, uint32t flags);
void csxRepGet32(acchandlet handle, uint32t *hostaddr, uint32t offset,
uint32t repcount, uint32t flags);
void csxRepGet64(acchandlet handle, uint64t *hostaddr, uint32t offset,
uint32t repcount, uint32t flags);
INTERFACE LEVEL
Solaris DI Specific (Solaris DI)
PARAMETERS
handle The access handle returned from
csxRequestIO(9F), csxRequestWindow(9F), or
csxDupHandle(9F).
hostaddr Source host address.
offset The offset in bytes from the base of the mapped
resource.
repcount Number of data accesses to perform.
flags Device address flags.
DESCRIPTION
These functions generate multiple reads of various sizes
from the mapped memory or device register.

Kernel Functions for Drivers csxRepGet8(9F)
The csxRepGet8(), csxRepGet16(), csxRepGet32(), and
csxRepGet64() functions generate repcount reads of 8 bits,
16 bits, 32 bits, and 64 bits of data, respectively, from
the device address represented by the handle, handle, at an
offset in bytes represented by the offset, offset. The data
read is stored consecutively into the buffer pointed to by
the host address pointer, hostaddr.
Data that consists of more than one byte 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 charac-
teristics.
When the flags argument is set to CSDEVAUTOINCR, these
functions increment the device offset, offset, after each
datum read operation. However, when the flags argument is
set to CSDEVNOAUTOINCR, the same device offset will be
used for every datum access. For example, this flag may be
useful when reading from a data register.
CONTEXT
These functions may be called from user, kernel, or inter-
rupt context.
