heya somebody
i wrote this procedure, but when i put a call for it in main(), compile
and run,
the program doesn't even finish the self-setting-up phase.
i use rhide, with -O3 tag.
here's the proc: (it's supposed to read a chain of int coords from file
fn, into
the chain based at blp).
typedef struct landp //points read from file
{
int relx,y;
landp * r; //right
};
void readland(char * fn,landp ** blp) //blp=baselandp
{
landp * lp;
*blp=NULL;
FILE * f=fopen(fn,"rb");
if (f)
{
int read;
fread(&read,2,1,f);
while (read!=0xffff)
{
if (*blp) lp=(lp->r=(landp *)malloc(sizeof(landp)));
else *blp=lp=(landp *)malloc(sizeof(landp));
lp->relx=read;
fread(&read,2,1,f); //not sure how to do it with direct pointer
access
lp->y=read;
fread(&read,2,1,f); //not sure how to do it with direct pointer
access
}
lp->r=NULL;
fclose(f);
}
}
i can't see any reason for this to happen... :-(
can you please tell me why?
