LQR_PROGRESS_SET_UPDATE(3)
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.
