NAME

       lqr_progress_set_update - execude custom code at regular steps during each rescaling
       operation

SYNOPSIS

       #include <lqr.h>

       LqrRetVal lqr_progress_set_update(LqrProgress* p, LqrProgressFuncUpdate update_func);

DESCRIPTION

       The function lqr_progress_set_update sets the hook update_func to the LqrProgress object
       pointed to by p.

       The function update_func is of type LqrProgressFuncUpdate, whose prototype is defined by:

           typedef LqrRetVal (*LqrProgressFuncUpdate) (gdouble completion_percentage);

       Each time that the function lqr_carver_resize(3) performs a rescale operation (recall that
       it can perform more than one rescale operation at each call) this function will be called
       at regular intervale, with the current completion percentage completion_percentage as an
       argument.

       The update step can be set with the function lqr_progress_set_update_step(3).

RETURN VALUE

       The return value follows the Liquid Rescale library signalling system.
