Not sure if is what you are looking for, but in case with the word 
"slice size" you mean "NALU size" in bytes, then you just have to 
monitor the variable "nalu->len" that represents the length of a NAL 
unit expressed in bytes (it contains also NAL header and, since it is an 
integer, the padding bits).
Hope this helps,
Luca.
