Specify a path for write file

Hi
i'm having this function:

Code:

---

int logger(char *log_prefix,char *buffer)
{
        printf("Logger: Logging Command...\n");
        time_t now;
        time(&now);
        FILE *file;
        file = fopen("log.txt","a+"); // apend file (add text to a file or create a file if it does not exist.
        //writes the "buffer" to the txt file and current time and log prefix ( either sent or received).
        fprintf(file,"Time/Date:%s# Command %s = %s\n",ctime(&now), log_prefix,buffer);
        fclose(file);
        printf("Logger: Command Logged, Check log.txt for more details.\n");
        return 0;
}

---

this function creates a txt file called log.txt, in the path that the .c file exist. how can i specify a path in which the file will be created?

this code

By specifying the filename you want created. If you want "../other_dir/log.txt", then say so.

Yes... :)

Code:

---

file = fopen("./path/log.txt","a+");

this is what i needed to change, :) thanks for the help
