I have the following .x file called paper.x . When I create a server in rpc in order to call the function the error below occurs
paperserverproc.c:23:5: error: conflicting types for ‘add_procedure_1_svc’ paper.h:46:15: note: previous declaration of ‘add_procedure_1_svc’ was here
#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 */
} = 0x20001234; /* Program number */
I call the procedure with this way and the line 23 is the line when I declare the function as below
#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)
This is the paper.h file generated by rpcgen and I dont know what's the problem in line 46 that it mentions
/*
* Please do not edit this file.
* It was generated using rpcgen.
*/
