C - remove() 不会删除 char *

Question

我试图用remove()删除一个文件，由于某种原因，当我给它一个char*中的路径时，它不起作用。这是我所拥有的:

#include<stdio.h>

int main(int argc, char *argv[]){ 

    const char * toDie = "/home/User/Desktop/todie.txt";

    int status = remove(toDie);

    if( status != 0 ){
        printf("Unable to delete the file\n");
    }
}

当我运行时它工作正常

 int status = remove("/home/User/Desktop/todie.txt");

有人可以解释一下吗？

您应该首先检查该文件是否存在，或者您是否提供了正确的路径或该文件的正确名称。

试试这个:

#include<stdio.h>
#include<stdlib.h>

int main(void){

    const char * toDie = "/home/User/Desktop/todie.txt";

    FILE *check = fopen(toDie, "r");

    if(!check){
        printf("There is no file with that name\n");

    }

    int status = remove(toDie);

    if( status != 0 ){
        printf("Unable to delete the file\n");
        exit(1);
    }else{
        printf("File removed successfully");
    }
}

也许你注意到我改变了:

int main(int argc, char *argv[]){}

与:

int main(void){}

因为，如果您不带参数运行该程序，则不需要:

(int argc, char *argv[])
