Hey!
I'm looking for some help on what I'm doing wrong as I'm new to C#. I'd really like it if you can explain why my code isn't working and then offer some help on how to fix it without "making it easy" for me ;o) I have to understand what's happening :oP hehe...
On to the problem:
I have a linked list containing pointers to lines read from a file. What I would like to do is copy these lines into a char.
Can I use *strcpy for this? The way I use *strcpy now isn't working; I'm not getting the entire text copied. Maybe the error isn't the strcpy but some other part of my code?
Here's the code I guess is relevant:
struct lenket{
struct lenket *neste;
char *dir;
};
struct lenket *liste = NULL, *siste = NULL, *pdp, *q;int main(int argc, char **argv)
{
FILE *fp;
char *everything;
unsigned int filesize;
char *p1, *p2;
char *filnavn = argv[2];
if ((fp = fopen(filnavn,"r")) != NULL) {
printf("Filen %s er åpnet.\n\n", filnavn);
fseek(fp, 0, SEEK_END);
filesize = ftell(fp);
p1=p2 = everything = malloc(sizeof(char) * filesize);
fseek(fp, 0, SEEK_SET);
fread(everything, 1, filesize+1, fp);
everything[filesize] = 0;
while(p1-everything < filesize){
if(*p1 =='\n'|| p1-everything == filesize-1 ){
if(*p1==0){
break;
}
*p1='\0';
pdp=malloc(sizeof(struct lenket));
pdp->neste=NULL;
pdp->dir=malloc(p1-p2+1);
strncpy(pdp->dir, p2, p1-p2);
if(liste==NULL){
liste=siste=pdp;
}else{
siste->neste=pdp;
siste=pdp;
}
p2=p1+1;
}else{
++p1;
}
}
pdp=liste;char *teksten = NULL;
teksten=malloc(sizeof(teksten)+1);
do {
*strcpy(teksten, pdp->dir);
printf("%s\n", pdp->dir);
} while((pdp=pdp->neste) != NULL);All help is appreciated! :o)
