|void tick_current||(||tickstamp_t *||ts)|
Calculates difference in ticks/subticks between two tickstamps.
This function can only calculate a valid difference if the 'end' timestamp hasn't crossed the 'begin' value. In other words: the maximum valid difference that can be calculated is bound by the upper limit of the tick type (uint_base_t). The upper limit of the type uint_base_t is always 2^N-1, where N is equal to the bit- with of the integer-registers on your system - as selected with the CORE_*BIT-parameter in glm_conf.h.
|begin||Pointer to variable holding an older tickstamp|
|end||Pointer to variable holding a more recent tickstamp.|
|result||Pointer to variable to which to store the difference.|
|float tick_time||(||const tickstamp_t *||ts)|
Converts a tickstamp into a time in seconds.
Note that this function assumes that the tick timer counts up. Therefore if CORE_SUBTICK_FUNC is defined in glm_conf.h ensure this function's return value is that of a up-counting timer. One can easily convert an down-counting timer value into an up- counting one by taking the one's complement of the down-counting timer value (known in C as inverse or ~).
