//I had something similar to this
typedef struct {
unsigned char field1;
TYPE3 field2;
unsigned char field3;
} CONFIGURATION;
typedef struct _INTERFACE {
CONFIGURATION *Configuration;
TYPE2 *Interface2;
} INTERFACES;
//I need to regroup the fields.
typedef struct {
unsigned char field3;
} GROUP2;
typedef struct {
unsigned char field1;
TYPE3 field2;
} GROUP;
typedef struct {
GROUP *fieldnew1;
GROUP2 *fieldnew2;
} CONFIGURATION2;
typedef struct _INTERFACE {
CONFIGURATION Configuration;
TYPE2 Interface2;
} INTERFACE2;
So, i need to replace the references.
INTERFACE2 *a;
a->Configuration->field1 <==> a->Configuration.fieldnew1.field1
a->Configuration->field2.boolean <==>
a->Configuration.fieldnew1.field2.boolean
a->Configuration->field3 <==> a->Configuration.fieldnew2.field3
