#include "mutnnn.h" #include "rdsnnn.h" #include "rwinnn.h" #include "rtlnnn.h" main() { rdsrec_list ∗Rectangle; rdswinrec_list ∗WinRec, ∗HeadWinRec; mbkenv(); rdsenv(); loadrdsparam(); WinRec = HeadWinRec = allocrdswinrec(); /∗ Fill the table with rectangles ∗/ for ( Counter = 0 ; Counter < RWI_MAX_REC ; Counter ++ ) { if ( Rectangle == (rdsrec_list ∗) NULL ) break; WinRec->RECTAB[Counter] = Rectangle; Rectangle = Rectangle->NEXT; } if ( Counter == RWI_MAX_REC ) { /∗ the table is full : allocation of a new table ∗/ WinRec->NEXT = allocrdswinrec(); WinRec = WinRec->NEXT; } . . . . }
