Couldn't create temporary file to work with

Make sure that the program has the necessary permissions to create files in the specified directory. Check if the directory exists and if the program has write permissions in that location. If needed, adjust the permissions using the appropriate system commands.

Here is an example of how to check for directory existence and permissions in C:

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

int main() {
    // Specify the directory path
    const char *directoryPath = "/path/to/your/directory";

    // Check if the directory exists
    if (access(directoryPath, F_OK) == -1) {
        // Directory does not exist
        perror("Error: Directory does not exist");
        return EXIT_FAILURE;
    }

    // Check if the program has write permissions in the directory
    if (access(directoryPath, W_OK) == -1) {
        // Program does not have write permissions
        perror("Error: No write permissions in the directory");
        return EXIT_FAILURE;
    }

    // Your code here...

    return EXIT_SUCCESS;
}

Replace "/path/to/your/directory" with the actual path to the directory you are working with. This code checks if the directory exists and if the program has write permissions in that directory. If any of the checks fail, an error message is printed, and the program exits with a failure status. Adjust the logic as needed for your specific requirements.
