I edite the gcc_nto*/Makefile
and added “-Bstatic -l ph -Bdynamic” to the link lines ( LDFLAGS=… and
SDFLAGS=… ), but it seems I get another pb whith the PtNumericFloat.
Here is my code :
/* Y o u r D e s c r i p t i o n /
/ AppBuilder Photon Code Lib /
/ Version 2.01 */
/* Standard headers */
#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
#include <string.h>
/* Local headers */
#include “ablibs.h”
#include “abimport.h”
#include “proto.h”
PtWidget_tlink_instance;
PtWidget_tNfich;
PtWidget_tg[3];
float gain[3];
FILEfile;
FILEaff;
char*nom;
int
gains_acquis( PtWidget_t *widget, ApInfo_t *apinfo, PtCallbackInfo_t
*cbinfo )
{
int l=0;
/* eliminate ‘unreferenced’ warnings */
widget = widget, apinfo = apinfo, cbinfo = cbinfo;
link_instance = ApGetInstance(widget);
Nfich = ApGetWidgetPtr(link_instance,ABN_gains_nom);
PtGetResource(Nfich, Pt_ARG_TEXT_STRING, &nom,0);
file = fopen(nom,“r+”);
fseek(file,47*sizeof(float),SEEK_SET);
g[l++] = ApGetWidgetPtr(link_instance,ABN_gains_kp);
g[l++] = ApGetWidgetPtr(link_instance,ABN_gains_kd);
g[l++] = ApGetWidgetPtr(link_instance,ABN_gains_ga);
//ABN_gains_kp and so are PtNumericFloat
l=0;
aff=fopen(“affich.txt”,“w”);
for(l=0;l<3;l++)
{
PtGetResource(g[l],Pt_ARG_NUMERIC_VALUE,&gain[l],0);
fwrite(gain[l],sizeof(float),1,file);
fprintf(aff,"%f \n",*gain[l]);
}
fclose(aff);
fclose(file);
return( Pt_CONTINUE );
}
But when I open affich.txt, I only obtain
0.0000
0.0000
0.0000
whatever I type in the widgets when running the application.
Then I tried something :
/* Y o u r D e s c r i p t i o n /
/ AppBuilder Photon Code Lib /
/ Version 2.01 */
/* Standard headers */
#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
#include <string.h>
/* Local headers */
#include “ablibs.h”
#include “abimport.h”
#include “proto.h”
PtWidget_tlink_instance;
PtWidget_tNfich;
PtWidget_tg[1];
int gain[1];
FILEfile;
FILEaff;
char*nom;
int
gains_acquis( PtWidget_t *widget, ApInfo_t *apinfo, PtCallbackInfo_t
*cbinfo )
{
int l=0;
/* eliminate ‘unreferenced’ warnings */
widget = widget, apinfo = apinfo, cbinfo = cbinfo;
link_instance = ApGetInstance(widget);
Nfich = ApGetWidgetPtr(link_instance,ABN_gains_nom);
PtGetResource(Nfich, Pt_ARG_TEXT_STRING, &nom,0);
file = fopen(nom,“r+”);
fseek(file,47*sizeof(int),SEEK_SET);
g[l++] = ApGetWidgetPtr(link_instance,ABN_gains_test);
// ABN_gains_test is a PtNumric Integer
l=0;
aff=fopen(“affich.txt”,“w”);
for(l=0;l<1;l++)
{
PtGetResource(g[l],Pt_ARG_NUMERIC_VALUE,&gain[l],0);
fwrite(gain[l],sizeof(int),1,file);
fprintf(aff,"%d \n",*gain[l]);
}
fclose(aff);
fclose(file);
return( Pt_CONTINUE );
}
I just added a PtNumericInteger in the window, and changed the code to write
this number instead of the three previious ones. Then I obtain an integer
equal to the one I type when running the application.
I don’t really need the .txt file, but I’m afraid that the other file
(fwrite(gain[l],sizeof(int),1,file)) won’t be written correctly. Is there
another thing to do so that PtNumericFloat would be accepted, or is there a
mistake in my code (sometimes I’m quite lost whith the format in functions)
?
