expected identifier or ‘(’ before numeric constant?

Question

I have this header file ... for some reason I keep getting an error saying log_server.h:48: error: expected identifier or ‘(’ before numeric constant I get this error on both lines defining the put_evt and print_evt_list functions, here's what the code looks like:

#ifndef _GENERIC
#define _GENERIC
#include <string.h>
#include <time.h>
#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
#endif

#ifndef _NETWORKING
#define _NETWORKING
#include <netinet/in.h>
#include <arpa/inet.h>
#include <netdb.h>
#include <sys/socket.h>
#include <sys/types.h>
typedef struct sockaddr SA;/* To make casting in the (bind, recvfrom, sendto) more readable */
#endif

#define LOGIN_EVT 0
#define LOGOUT_EVT 1

#define RECV_MSG 27
#define SEND_MSG 64000
#define MAX_EVT_COUNT 3000

struct evt{ 
    char user_name[8];
    int type;
    long int time;
};



/* open log file to append the events to its end
 * return 0 on success and -1 on failure (file could not be opened)
 */
int init_log(const char *log_fname);

/* closes the log file
 * return 0 on success and -1 on failure (file could not be opened)
 */
int terminate_log();

/* add new event to the log file
 * return 0 on success and -1 on failure
 */
int put_evt(struct evt *e);

/* get list of events that occured after the given time
 * count is the size of the allocated and passed e-list
 * return number of found events on success and -1 on failure
 */
int get_events(struct evt  *e_list, long int time);

/* print given event's info (name, time)*/
void print_evt(struct evt  *e);

/* print "count" event's info from the given e_list info (name, time)*/
void print_evt_list(struct evt  *e_list, int count);

/* startListen takes a port number and returns a listening descriptor on sucess or negavtive on error  */
int startListen(int port);

/* Responsbile for hanlding received messages from clients and responding to them accordingly
if the message is an action done, it'll save it in the log file and notify the client
if the message is a query about the events, it'll call the private function queryHandler(); to handle it
returns negative on ERROR*/
int handle_message(int sockDescriptor, struct sockaddr_in *client, char *recvMessage);

I've read that this error can be caused by having a preprocessing directive written on more than one line ... but I don't have that. Any idea what I'm doing wrong?

Answer 1

the problem was that I had struct evt declared in another location.
