# kernelv_get_acs_target_positions()

## Prototype

KERNELV_RETURN | kernelv_get_acs_target_positions (unsigned long* positions, unsigned long maxByteSize, unsigned long* returnSize);

## Description

The ACS target positions of all axes existing in the CNC are returned in an array.

The target position is the axis position at the end of the currently executed motion block.

Position values have a resolution of 0.1 µm for translatory axes or 1*10-4° for spindles or modulo axes.

The error code ERR_CNC_RET_MEMORY is returned if the memory provided by the calling application is not sufficient for returning all values.

The calling application must provide at least number of axes * sizeof(signed long int) bytes for returning of all position values.

The order of the axis positions in the returned array is equal to the configuration order of the axes.

## Parameter

Name | Type | Meaning
positions | unsigned long* | Pointer to the memory area for the axis positions to be returned.
maxByteSize | unsigned long | Size of the memory area for the axis positions.
returnSize | unsigned long* | Number of bytes returned in positions.

## Return values

Symbol | Value | Meaning
RET_FINISHED | 0 | The function was executed without error.
ERR_CNC_NOT_INIT | -3 | The simulation CNC kernel was not yet initialised.
ERR_CNC_RET_MEMORY | -4 | The return value(s) does/do not fit into the memory provided. In this case, the required memory is returned in the returnSize parameter.
