c - Typedef of structs -

i using structs in project in way:

typedef struct {     int str1_val1;     int str1_val2; } struct1; 

and

typedef struct {     int str2_val1;     int str2_val2;     struct1* str2_val3; } struct2; 

is possible hack definition in way, use types code, like

struct2* a; = (struct2*) malloc(sizeof(struct2)); 

without using keyword struct?

yes, follows:

struct _struct1 { ... }; typedef struct _struct1 struct1;  struct _struct2 { ... }; typedef struct _struct2 struct2;  ...  struct2 *a; = (struct2*)malloc(sizeof(struct2));
