Hi,
I'm new in kernel coding (i'm making a kernel module) so i had to learn how
to use MALLOC*() macros to get memory, not very difficult in fact. But when
the moment of making a chained list came, the first difficulty appears :/
Before, i made chained lists like that:
struct my_type {
struct my_type *next;
char elem[32];
int elem_flags;
};
struct my_type *ch_list;
struct my_type *add_2_list(char *elem, int flags) {
struct my_type *chelem;
chelem = (struct my_type *) malloc(sizeof(struct my_type));
chelem->elem_flags = flags;
strncpy(chelem->elem, elem, 32);
chelem->next = (struct my_type *) ch_list;
ch_list = (struct my_type *) chelem;
return((struct my_type *) chelem);
}
(sorry if my code disturbs somebody but i want to be very clear)
So my question is: Is there a way to *port* this code to be compatible with
kernel code ? With MALLOC*() macros, i cannot use this code directly because
each buffer has his own structure (i mean M_MYBUF)... So i looked at the
queue(3) manpage ... but i want to know if i can *port* my code before.
