void TeX_sizeSimple(char *element, int *width, int *height, int *line).// A pixel of spacing was added for each element, but the last one didn't need one.// Freeing the allocated memory and preparing the next iteration.// Getting the properties of the found element and adapting existant properties for the expression.// Getting copied data of the next element in the pointer element.char *element // This pointer will contain dynamically-allocated temporary data - the text of an element.char *next // This pointer will parse the expression with expr.int tw, th, tl // These variables store temporary data needed for comparison between elements.int w=0, h=0, l=0 // These variables will contain the final properties of the expression.** needs at least one level of subsequent calls to TeX_sizeSimple().Therefore, the call stack is supposed unlimited.
