的輸出我寫了這個代碼，但是當試圖編譯它，它會返回THID錯誤：結構作爲一個功能

:24:8: error: conflicting types for ‘safe_syscall’ 
:19:10: note: previous implicit declaration of ‘safe_syscall’ was here

我指定的行數。

typedef struct syscall ditem; 

void safe_syscall_set (vmi_instance_t vmi) 
{ 
    ditem *head,*tmp = NULL; 
    char *name; 
    int num; 
    FILE * fp; 
    fp = fopen ("syscall.list", "r");//file including syscall names and numbers in format "name number" 
    //read file of syscalls and numbers 
    while(fscanf(fp, "%s %d",name, &num)!= EOF); 
    { 
     tmp = head; 
/* 19 */ 
     head = safe_syscall(name,num,tmp,vmi); 
    } 
    return; 
} 

/* 24 */ 
ditem *safe_syscall (char *syscall,int num,ditem *head,vmi_instance_t vmi) 
{ 
    uint64_t *sys_call_table = 0xffffffff816003e0; 
    uint64_t *memory = (uint64_t *) malloc(sizeof(*sys_call_table)); 

    char *path = "/home/ossl5/sysmap";//hardcoded 
    FILE *fp; 
    fp=fopen(path,"r"); 
    if(!fp) 
    { 
     printf("ERROR CAN NOT OPEN SYSTEM.MAP FILE\n"); 
     goto exit; 
    } 
    curr = (ditem *)malloc(sizeof(ditem)); 
    curr->num = num; 
    curr->next = head;//new nodes are being added to head of the list 
    head = curr; 
    curr->sys_name = syscall; 
    //Calculating syscall handler size 
    curr->size = sys_routine_size(fp,syscall,num); 
exit: 
    return head; 
}

我猜東西是錯誤的結構作爲output.This結構是一個鏈表，每個調用safe_syscall功能，新節點添加到列表的頭部和新頭由該函數返回的時間。

是什麼'24'這裏'24 ditem * safe_sys' –

@GrijeshChauhan語法錯誤。 – 2013-07-20 08:47:51

我認爲19和24是錯誤消息中指示的行號。 - 可能應該把它們放在評論中;-) – John3136

您還沒有宣佈safe_syscall()所以假定返回一個int。嘗試在第一次通話之前發出聲明ditem *safe_syscall (char *syscall,int num,ditem *head,vmi_instance_t vmi);。
