how do you put struct pointers into functions?

This is my struct

Code:

typedef struct{
char first[20];
char last[20];
int nums[6];
}RECORD; 

this is my function prototype

void writeRecord (RECORD* , FILE*, int);
this is my functions

Code:

void writeRecord (RECORD* people, FILE* fp, int num_people){
...................
} 
in my main i put
 	Code:
 	RECORD* people;

people = (RECORD*) malloc(num_people*sizeof (RECORD));

writeRecord(people, fp, num_people); 

can you guys tell me where i'm going wrong.

these are the errors i get in microsoft visual c++ 2008

these all point to the prototype
syntax error: ')'
syntax error: ','
syntax error: missing ')' before '*'
syntax error: missing '{' before '*'

these point to the function
writeRecord: redifinition; different basic types
