This will let you create a box and position it somewhere on the screen.
The text_buffer is a pointer to a character array and needs to be as long as
AT LEAST MAX_CHARS + 1.If the text_buffer is smaller, it will crash if user
types more characters than what will fit into the text buffer.
Allocating buffer space automatically so that programmer can be carefree now.
This also automatically adjusts the size of edit box so that it can hold enough characters.
All you need is :
tlx,tly = Coordinates of the beginning of the edit box.
max_chars = Limit of number of characters user can enter into edit box.
