static structure in C keep list of information in memory

Hello everyone,

I would like to know how I can create a static data type structure where the information is always kept in memory even if it calls different functions or executes some other code outside its main function.

Every time I call a function the data is lost on the list.

typedef struct director_users dir_users;
struct director_users
	int count;				        //Id
	char name[10];			        //Name
	char time1[10];			        //Pos
	struct director_users *p1;
static dir_users *directorio=NULL;

When I create the linked list the information is stored correctly but when calling another function the information disappears from the list.
