I am trying to get a procedure working to read and write records to the
disk.  This is accomplished in many books by using fwrite and fread.
The sample below comes from one of the books...the problem is:

On SAS C, the first argument in fwrite or fread which is &grades or something
like that in this case gives a warning 88:  argument type incorrect

This is standard C code so I am confused as to why SAS doesn't like it.
Any other ideas?  I tried using fscanf, but the problem there is that
a space ends reading in a string, and my strings my have 0, 1, or more
spaces in them.
The material being written in my case consists of 5 integers and 2 strings
(char arrays of [51] and [25] ) for however many entries there are.

anyway, here is the other one below.
(both mine and this give the same warning)
#include <stdio.h>
main ()
{
 typedef struct {
       char name[15];
       int midterm;
  } grades;
int i,number;
char name[50];
grades student;
FILE *fp;
printf("class file  ");
scanf("%s",name);
if (NULL!=(fp=fopen(name,"w"))) {
   printf("number of students");
   scanf("%d",&number);
   for (i=0;i<number;i=i+1) {
     printf("student's name:  ");
     scanf("%[^\n]",student.name);
     printf("midterm score:  ");
     scanf("%d",&(student.midterm));
     fwrite (&student,sizeof(student),1,fp);
   }
   fclose(fp);
} else
   printf("trouble opening the file\n");
}

There is the book sample.
As I said, where you see the fwrite (&student,sizeof(student),1,fp);
it gives the warning for the &student
