RPC - 衝突類型錯誤

我有以下.x文件，名爲paper.x。當我以撥打以下錯誤時，函數創建RPC服務器RPC - 衝突類型錯誤

paperserverproc.c：23：5：錯誤：衝突的類型「add_procedure_1_svc」 paper.h：46：15：注意：先前的「add_procedure_1_svc」宣言在這裏

#include <limits.h> 
struct paper_saved{ 
    char author_name[CHAR_MAX]; 
    char paper_title[CHAR_MAX]; 
    int paper_id; 
    char paper_file_name[CHAR_MAX]; 
    char paper_content[CHAR_MAX]; 
}; 
struct paper_info_saved{ 
    char author_name[CHAR_MAX]; 
    char paper_title[CHAR_MAX]; 
    int paper_id; 
    char paper_file_name[CHAR_MAX]; 

}; 
struct list_papers{ 
    paper_saved paper; 
    struct list_papers *next; 
}; 

program PAPER_PROGRAM 
{ 
    version PAPER_VERSION 
    { 
    int ADD_PROCEDURE(paper_saved) = 1;  /* Procedure nb */ 
    void LIST_PROCEDURE(void)=2; 
    paper_info_saved INFO_PROCEDURE(int)=3; 
    paper_saved FETCH_PROCEDURE(int)=4; 
    void REMOVE_PROCEDURE(int)=5; 
    } = 1;        /* Version nb */ 
} = 0x200;      /* Program number */

我打電話的方法，用這種方式和行23行，當我宣佈函數如下

#include <stdio.h> 
#include <stdlib.h> 
#include <string.h> 
#include <unistd.h> 
#include "paper.h" 
#include <ctype.h> 
#include <limits.h> 
....... 
int add_procedure_1_svc(paper_saved *paper_pointer, struct svc_req *rqstp)

這是通過的rpcgen產生的文件paper.h，我不知道那是什麼它提到

/*

* It was generated using rpcgen.

在第46行的問題，所以正確的.h文件中是

#include <limits.h> 
struct paper_saved{ 
    char author_name[CHAR_MAX]; 
    char paper_title[CHAR_MAX]; 
    int paper_id; 
    char paper_file_name[CHAR_MAX]; 
    char paper_content[CHAR_MAX]; 
}; 
struct paper_info_saved{ 
    char author_name[CHAR_MAX]; 
    char paper_title[CHAR_MAX]; 
    int paper_id; 
    char paper_file_name[CHAR_MAX]; 

}; 
struct list_papers{ 
    paper_saved paper; 
    struct list_papers *next; 
}; 
typedef int p_id; 
program PAPER_PROGRAM 
{ 
    version PAPER_VERSION 
    { 
    p_id ADD_PROCEDURE(paper_saved) = 1;  /* Procedure nb */ 
    void LIST_PROCEDURE(void)=2; 
    paper_info_saved INFO_PROCEDURE(int)=3; 
    paper_saved FETCH_PROCEDURE(int)=4; 
    void REMOVE_PROCEDURE(int)=5; 
    } = 1;        /* Version nb */ 
} = 0x200;      /* Program number */

該函數聲明爲返回int：

int add_procedure_1_svc(paper_saved *paper_pointer, struct svc_req *rqstp)

但extern爲返回int*

extern int * add_procedure_1_svc(paper_saved *, struct svc_req *);

其中之一肯定是錯誤的。

男人就是這個問題！你是對的！我應該在.h文件的typedef int p_id中添加一個lin，並將p_id設置爲該過程的返回值。謝謝！ @BinyaminSharet –

什麼文件紙行46 .h有？。檢查第46行的paper.h文件以查看函數簽名是否相同。是否由rpcgen自動生成？

我已經添加了由rpcgen生成的paper.h文件。如果你能找到問題的人，我會很高興。 @RanjithRuban –
