hi.
i am just using my free time to code with alpm and alpm_list. nothing to be published yet (or ever ?)
today i just noticed that a list created with alpm_list_new has a number of element of 1 as alpm_list_count reports it: #include <stdlib.h> #include <stdio.h>
#include <alpm_list.h>
int main(void) { alpm_list_t *l; l = alpm_list_new(); printf("count=%d\n",alpm_list_count(l)); return(0); }
$ ./test count=1
shining wanted me to post here about that. that's done !
Yes, this is not nice, but needed (we doesn't have alpm_list_node_t or alpm_list_head_t struct): list == NULL is not allowed [otherwise list->data or list->next would lead to a segfault.] Workaround: alpm_list_count could count nodes with not-NULL data pointers only. Btw, this also indicates a more serious bug: as I see, if you remove the only element from a 1-element list, alpm_list_remove() will return with NULL, with is not a valid list pointer... Bye
