I do not have time to supply a complete code example, but I can
provide some more hints. The user of ProfileImage() needs to copy the
entire ICC profile from disk into memory somehow. For example, this
may be accomplished via fopen() & fread(). The 'datum' argument is
the address in memory where the profile has been loaded, and the
length argument is the size of the profile in memory.
In addition to ProfileImage(), ImageMagick provides SetImageProfile()
which can be used to attach an initial profile to the image without
applying any CMS transforms.
You can use GetImageProfile() to gain access to an existing profile
which is attached to the image. This is useful in order to know if
the image already had a profile, or perhaps if you want to use the
same profile for other things.

Thanks for advices, code implementation was easy and is working fine
now, but...I met some strange things in converssion tiff file with LAB
to the RGB colorspace. Colours change in strange way and are not
correct. Colorspace conversion works, becouse I checked it with couple
of different ICC-RGB profiles and allways image colours were changed.
I tried to apply LAB color profile first and than convert to RGB
(colorspace conversion made twice), but nothing happened, colours were
still .
If you want I can send that tiff file to you...so you can check that...
If I open this file in Photoshop 7 and save it later after conversion
everything is ok.
Best regards
Michal
