本文导语: #include #include #include int main(void) { FILE *fp; fp = fopen("/spms/idep/log/ftp_client/log/collect_20090815_00031.list","r"); if(NULL == fp) { printf("Open file failednn"); } char path[4096]; if( fgets(path,4096,fp) == NULL ) { ...

int main(void)
{
FILE *fp;
fp = fopen("/spms/idep/log/ftp_client/log/collect_20090815_00031.list","r");
if(NULL == fp)
{
printf("Open file failednn");
}
char path[4096];
if( fgets(path,4096,fp) == NULL )
{
printf("Failed nn");
}
else
{
printf("The path is %snn",path);
printf("The length of the path :is %d n",strlen(path));
}
return 0;
}
我文件当中存的内容是：

我想把它全部读取出来，但是上面的程序只能读取出第一行信息。我该怎办呢？？？？？

if(NULL == fp)

char path[4096];
while( fgets(path,4096,fp) != NULL )
{
printf("%s",path);

你输出的信息要放到什么位置吧！ 再说文件也没关闭！

fgets只读一行～～
写个循环就可以了

你的循环呢
fgets可是读到换行符就结束的
