一个线性链表的初始化程序，运行时显示“Segmentation fault" ,代码如下：
# include
# include
# include
# include
# define TRUE 1
# define FALSE 0
# define OK 1
# define ERROR 0
# define OVERFLOW -1
struct sqlist
{
int * p;
int length;
int listsize;
}sqlist;
int Initlist_sq(struct sqlist * L, int LIST_INIT_SIZE)
{
L->p = (int * )malloc(LIST_INIT_SIZE * sizeof(int));
if ( L->p== NULL ) exit(OVERFLOW);
L->length = 0;
L->listsize = LIST_INIT_SIZE;
return OK;
}
void main()
{
struct sqlist * p;
int status = 0;
status = Initlist_sq(p, 100);
if( status)
printf("memory allocation succeed\n");
else
printf("memory allocation failed\n");
}
