Can not open the directory? about wasmedge HOT 5 CLOSED

Please post source code next time, especially your C file is short.

I don't understand your environment, --dir=./Data will use Data/ as current directory from my understanding, and your code is trying to open a file named Data. Might you expand more?

In this sense, you will need to provide full steps including how you prepare your file system for the program.

Thanks for your reply!
The c file is already uploaded a s test-c.txt, and the wasm file is already uploaded as test-wasm.txt, since .c and .wasm file cannot be uploaded. Please download the file and change the suffic.

No, I mean you can just post C code in code block.

Ok, here's the c code:

#include <stdio.h>
#include <fcntl.h>
#include <unistd.h>
#include <sys/stat.h>

int path_remove_directory(int basedir_fd, const char *file_name) {
    if (unlinkat(basedir_fd, file_name, AT_REMOVEDIR) == -1) {
        printf("Error deleting file.\n");
        close(basedir_fd);
        return 1;
    }

    printf("File deleted successfully.\n");
    return basedir_fd;
}

int get_fd(const char* file_name, int open_style){
    int fd = open(file_name, open_style);
    if (fd == -1) {
        perror("Failed to open the file.\n");
    }else{
        printf("Successfullly get the fle fd.\n");
    }

    return fd;
}

int main() {
    const char* file_name = "Data";
    int open_style= O_RDWR;
    int fd = get_fd(file_name, open_style);

    if (fd != -1){
        const char *file_name = "tmpdir";
        path_remove_directory(fd, file_name);
    }
    
    return 0;
}

This is not a bug with WasmEdge, you just need to change your O_RDWR to O_RDONLY. bytecodealliance/wasm-micro-runtime#2884
