CSX_REPPUT8 9F "Jul 19, 1996"
NAME
csx_RepPut8, csx_RepPut16, csx_RepPut32, csx_RepPut64 - write repetitively to the device register
SYNOPSIS
#include <sys/pccard.h>



void csx_RepPut8(acc_handle_t handle, uint8_t *hostaddr, uint32_t offset,
 uint32_t repcount, uint32_t flags);

void csx_RepPut16(acc_handle_t handle, uint16_t *hostaddr, uint32_t offset,
 uint32_t repcount, uint32_t flags);

void csx_RepPut32(acc_handle_t handle, uint32_t *hostaddr, uint32_t offset,
 uint32_t repcount, uint32_t flags);

void csx_RepPut64(acc_handle_t handle, uint64_t *hostaddr, uint32_t offset,
 uint32_t repcount, uint32_t flags);
INTERFACE LEVEL
illumos DDI Specific (illumos DDI)
PARAMETERS
handle

The access handle returned from csx_RequestIO(9F), csx_RequestWindow(9F), or csx_DupHandle(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 writes of various sizes to the mapped memory or device register.

The csx_RepPut8(), csx_RepPut16(), csx_RepPut32(), and csx_RepPut64() functions generate repcount writes of 8 bits, 16 bits, 32 bits, and 64 bits of data, respectively, to the device address represented by the handle, handle, at an offset in bytes represented by the offset, offset. The data written is read consecutively from 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 characteristics.

When the flags argument is set to CS_DEV_AUTOINCR, these functions increment the device offset, offset, after each datum write operation. However, when the flags argument is set to CS_DEV_NO_AUTOINCR, the same device offset will be used for every datum access. For example, this flag may be useful when writing to a data register.

CONTEXT
These functions may be called from user, kernel, or interrupt context.
