CO_REGISTER_WRITE

 co_error co_register_write(co_register reg,                            const void *buffer,                            size_t buffersize);

Description

This function writes a data value from a local variable to a register object. This function must be called from within a process run function.

Arguments

The arguments for co_register_write are as follows:

co_register reg	A pointer to a register object as passed on the process argument list.
const void *buffer	A pointer to the source memory. (The source is typically an integer variable.)
size_t buffersize	The number of bytes to transfer in the write operation.

Return Value

Returns co_err_none on success. Returns co_invalid_arg if the reg argument is NULL (co_errno: CO_ENULL_PTR) or the register is smaller than buffersize bytes (CO_EINVALID_REGISTER_WIDTH).
