[pushparaj muthu]

Hi 



I have created image on window by using Grlines nano -X API . I wanted to save 
image from window to  particular file . 





As per carlo mail dated on 14 wed 2007



I have enabled LINK_APP_INTO_SERVER  =Y 

and also  used two API GrNewPixmap and GrCopyArea  in my code



I could not able to save image in  file



Herewith my code 



void SaveFileFunction(void )

{

        

        void  *localbuf;



        localbuf = malloc(480000);

        

        if(!localbuf)

        {

               printf("\n Could not allocate memory \n");

               exit(0);

        }

       

        filefd      = open ("testfile.bmp", O_RDWR);

        if (filefd <= 0)

        {

                printf ("\n Unable to open the current  file \n");

                exit(0);

        }

        

        mapid = GrNewPixmap(600,800 , localbuf);

        

        GrCopyArea(w,gc,0,0,600,800,mapid,0,0,MWROP_SRCCOPY);

         

        writecont  = write (filefd,(void *)localbuf, sizeof(localbuf));

   

        if (writecont <= 0)

        {

                printf ("\n Unable to write content \n");

                exit(0);

        }

        free(localbuf); 



        close (filefd);

}

 



Pls do point any mistake i have made .
