誤差FSEEK

Question

用下面的代碼，我試圖從文件中讀取4個字節：

FILE *f 

uint32_t read_program(int A) 
{ 
    long i; 
    uint32_t strofprog; 
    uint8_t tmp; 
    i = 4*A; 
    fseek(f,i,0);// set a position in file 
    if((tmp = getc(f)) != EOF) 
    { 
     while((i%(4*A)) < 4) 
     { 
      fseek(f, i, SEEK_SET); 
      tmp = getc(f); 
      strofprog = tmp; 
      strofprog <<= 8; 
      i++; 
     } 
     return strofprog; 
    } 
    else 
    { 
     fclose(f); 
     return -1; 
    }; 
} 

然而，當我運行它，它會導致以下錯誤：

main.c: In function ‘read_program’: 
main.c:77: error: incompatible type for argument 1 of ‘fseek’ 
/usr/include/stdio.h:722: note: expected ‘struct FILE *’ but argument is of type ‘FILE’ 

什麼我做錯了，我該如何解決？ 85

線在貼：

fseek(*f,i,0);// set a position in file
