KDATA_ARRAY_FILL(3)	     Library Functions Manual	     KDATA_ARRAY_FILL(3)

NAME
     kdata_array_add,	     kdata_array_fill,	      kdata_array_fill_ydoubles,
     kdata_array_fill_ysizes, kdata_array_set -- modify array data source

LIBRARY
     libkplot

SYNOPSIS
     #include <cairo.h>
     #include <kplot.h>

     int
     kdata_array_add(struct kdata *data, size_t pos, double y);

     int
     kdata_array_fill(struct kdata *data, void *arg,
	 void (*fp)(size_t, struct kpair *, void *));

     int
     kdata_array_fill_ydoubles(struct kdata *data, const double *ys);

     int
     kdata_array_fill_ysizes(struct kdata *data, const size_t *ys);

     int
     kdata_array_set(struct kdata *data, size_t pos, double x, double y);

DESCRIPTION
     The    kdata_array_add,	kdata_array_fill,     kdata_array_fill_ydoubles,
     kdata_array_fill_ysizes,  and  kdata_array_set functions modify the buffers
     of a data source created by kdata_array_alloc(3).	kdata_array_fill invokes
     the fp function with  each  bucket  provided  by  kdata_array_alloc,  while
     kdata_array_add  and  kdata_array_fill directly modify the buckets at posi-
     tion pos.	The kdata_array_fill_ydoubles  and  kdata_array_fill_ysizes  set
     values to the corresponding array indices, which are assumed to be the same
     length as the data source (else the behaviour is undefined).

RETURN VALUES
     kdata_array_fill,	kdata_array_fill_ydoubles,  kdata_array_fill_ysizes, and
     kdata_array_set return 0 if they have any dependants  whose  update  fails,
     the  positions fall outside of the allocated boundaries, or the data source
     was not created with kdata_array_alloc(3); otherwise they return 1.
