invalid use of struct

[ngay528]

I am getting an "Invalid Use of Struct" on my "instrument" text.

typedef struct 

{

device dev;

char *name;

unsigned short int channels;

} instrument;

typedef struct 
{
	device dev;
	char *name;
	unsigned short int channels;
} instrument;

And device is created in an includ file and contains teh following

typedef int device; enum
{
	E3648A = 1,
	AG66321B = 0,
	AG66321D = 0,	//Same functions as 66321B
	PST3202 = 2								   
}

[ebalci]

typedef enum

{

E3648A = 1,

AG66321B = 0,

AG66321D = 0,

PST3202 = 2

} device;

typedef struct 

{

device dev;

char *name;

unsigned short int channels;

} instrument;

Hi,

I got your code and re-arranged it a little.

The following code did not generate any compile errors on CVI 6.0 which is the only version I have on this machine.

Make sure the device enum is defined before the compiler works on instrument struct.

Otherwise it cannot understand what a "device" is.

typedef enum
{
  E3648A = 1,
  AG66321B = 0,
  AG66321D = 0,
  PST3202 = 2
} device;

typedef struct
{
  device dev;
  char *name;
  unsigned short int channels;
} instrument;
