How can I delete a file pointed to by a FILE* in C?

Question

#include<stdio.h>

int main() {

    FILE* fp;
    fp = fopen("temp.txt", "w");
    fprintf(fp, "Hello, World!\n");

    // remove("temp.txt");  this requires the filename as an argument
    // removefile(fp);      <--- is something like this possible?

    return 0;
}

The remove function (defined in stdio.h) takes the file name as a parameter, but not the file pointer itself.

Is there some function in the C standard libraries that does file deletion, and takes file pointer as the arguement?

Answer 1

I don't believe there's any way to do this, because a FILE* may not necessarily correspond to a file in the filesystem at all (For example, stdin and stdout).

And in filesystems that support hard links, there can be multiple paths referring to the same underlying file, which one would you want it to remove?
