Question

gcc 4.4.4 c89

Not sure why I am getting this error.

In my header file I have the following

handle.h

typedef struct Handle_t Handle

In my implementation file

handle.c

struct Handle {
    size_t id;
    char *name;
};

Handle* create_handle(size_t id)
{
    Handle *hdev = NULL;
    hdev = malloc(sizeof(*hdev)); /* Error */
    .
    .
}

Many thanks for any suggestions,

I used to get the typedef wrong often until I started to think of it like two parts: type and def. The type first, then the definition of a new name.

typedef <type> <name>;
typedef struct Handle Handle_t; /* defines Handle_t as struct Handle */
typedef char *c_string;         /* defines c_string as char * */
