DESCRIPTION
im_histlin(3) formats its arguments as printf(3), appends " # time-and-date", and appends the whole line of text to the image history. The string is typically the command-line action that would be required to do whatever it is that you've just done to the image.im_updatehist(3) is given a standard argc/argv, formats them appropriately, and calls im_histlin(3) for you. Note that the program name is passed separately.
im_history_get(3) returns the entire history of an image as a single C string, one action per line. No need to free, but you mustn't modify either.
RETURN VALUE
The function returns 0 on success and -1 on error.SEE ALSO
