structure and pointers in C -

seg fault again!! please see , correct me

typedef struct entry_s {     int key;     int value;     struct entry_s *next1; } entry_t;  entry_t *next2; next2=malloc(sizeof(entry_t)); next2->key=key;  // giving seg fault now... 

thanks

sizeof(entry_t *) gives 4 bytes nothing size of pointer. need change malloc statement this:

next2=malloc(sizeof(entry_t ));

after malloc add following statement.

memset(next2, 0x00, sizeof(entry_t)) 

now not segfault.
