va_list problem, I need your help! in C language. Thank you!

Use variable-length argument lists (va_list) to write a function node *create_ssi(int N, ...) such that a singly linked list of N nodes is created. Assume the node structure is as follows: struct node { struct node *next; int data; Also show how to call the function. Ava list example: void errmsg(int code, ...) va list ap: char * Emt, va_start(ap, code): if (code&FILENAME) (void)fprintf stderr, "\"%s":", arg(ap, char")); if (code&LINENUMBER) (void)forintfi stderr, "%d", va argiap, int): if (code&WARN) (void)fputs("Waming:".stderr); Imt-va_arg(ap. char : (void) vfprintf stderr, fimt, ap): va_end(ap)
