segmentation fault...

[Ram]

Hi,

please find the following snippet code:

typedef struct {
int mode;
int uid;
int gid;
char prefix[MAX_NAME_LENGTH];
} config_objects;

config_objects *config_rules = NULL;

char temp_buf[1024];

const char delimiters[] = ":";


//temp_buff contains--> 00770:1000:2001:"cache"


token = strtok (temp_buf, delimiters);
config_rules->mode = atoi(token); --> segmentation fault??

Can any one please explain, why i am getting segfault here?

Thanks in advance!

If config_rules is NULL, then config_rules->mode is not a valid
storage location. Perhaps you should allocate a structure for
config_rules to point at.
