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.
