It looks like I have a memory leak when I try to initializ an array of pointers. This my code:
void initLabelTable(){
register int i;
hashNode** hp;
labelHashTable = (hashNode**) malloc(HASHSIZE*sizeof(hashNode*));
hp = labelHashTable;
for(i=0; i<HASHSIZE; i++) {
*(hp+i) = NULL;
}
}
Update:
I have this code:
c = fgetc(fp);
printf("%c",c);
line[MAXIMUM_LIN开发者_如何转开发E_LENGTH] = '\0';
initLabelTable();
c = fgetc(fp);
I get a segmentation fault on last row although the first getc succeeds.
When I watch fp
I see a different address. Any ideas?
No, this function by itself doesn't leak any memory. It allocates memory for labelHashTable
, which, according to it's name, is what it's supposed to do.
Make sure that the memory pointed to by labelHashTable
is freed once you're finished using it, else you will have a memory leak there. Also don't call initLabelTable()
repeatedly without freeing labelHashTable
before each subsequent call.
