Color Space definition of LibRAW coefficients

Hi guys,

can somebody help me with problem around convert camera RGB values (as shot, white point) to known color space.

When I converting As shot coefficients to sRGB I use:
RawProcessor->imgdata.color.cam_mul[] then use matrix
RawProcessor->imgdata.color.rgb_cam[][] to convert as sRGB. But I don't know if it is D65 or D50 illuminant or other?

White point rawProcessor->imgdata.color.pre_mul[] is with which color space? Camera or sRGB and which illuminant?

I can not find this information anywhere. Currently I am suppose that both coefficients are in camera space and conversion with rgb_cam[][] convert it to D65.

Thank you for help
Ladislav
