The QuickC example program RECORD2.C modifies memory pointed to by an
uninitialized pointer (recpos). RECORD2.C is the example program in
on-line help for the functions fgetpos and fsetpos.
If this program is executed with pointer check enabled, execution may
terminate with the following diagnostic displayed:
run-time error R6013
- illegal far pointer use
If RECORD2.C is executed without pointer check enabled, the system may
crash, or it may appear to execute successfully.
To correct this problem add an additional header file, as
follows:
#include <malloc.h>
Also, replace the line
fpos_t *recpos;
with the following:
fpos_t *recpos = malloc(sizeof(fpos_t));
