redhat9下如何使用timer

wangjinyi

[code:1]#include <stdio.h>
#include <stdlib.h>
#include <linux/timer.h>
void showint(unsigned long i)
{
       printf("%c",'.');
}

int main(void)
{
       timer_t *tl = (timer_t*)malloc(sizeof(timer_t));
       init_timer(tl);
       tl->expires = 100;
       tl->function = showint;
        add_timer(tl);
       return 0;
}

Makefile 文件:
TARGETFILE = mytest
SRC = mytest.cpp
CC = g++
CCOPT = -g
INCLS = -I.
LIBS =
DEFS =
CFLAGS = $(CCOPT) $(INCLS) $(DEFS)
all:
       $(CC) $(CFLAGS) $(SRC) -o $(TARGETFILE) $(LIBS)
clean:
       rm -f *.o $(TARGETFILE) *.bak

请大家帮忙看看，好像是与time.h的定义冲突造成的，但是我指定使用的是/linux/timer.h，怎么回事呢，如果用gcc，有同样的错误，谢谢大家了。
