# kernelv_ch_resume()

## Prototype

KERNELV_RETURN | kernelv_ch_resume (unsigned long int chanIndex);

## Description

The program currently running in the channel is continued. The channel state changes to SIMU_CNC_STATE_ACTIVE.

A program can only be continued if the channel is in the SIMU_CNC_STATE_HOLD state. The function returns the value ERR_INVALID_STATE if it is called while the channel is in another state.

## Parameter

Name | Type | Meaning

RET_FINISHED | 0 | The function was executed without error.
RET_BUSY | 1 | The function is currently being executed, but has not yet been completed. The API function must continue to be called.
ERR_INVALID_CHAN | -1 | The transferred channel index is higher than the number of configured channels - 1
ERR_CNC_NOT_INIT | -3 | The simulation CNC kernel was not yet initialised.
