Try to save a text to a file, but the file path or directory might be wrong.

Could anyone help me to check the file_path, which is correct or not?

                         FILE* f= fopen("/shared/documents/save.dat", "wb");
                           if(f==NULL){
                             fprintf(stderr,"Cannot create output.txt\n");
                             _exit(1);
                           }
                           fprintf(f,"Hello World!");

 

The result always show f == NULL.

Re: Try to save a text to a file, but the file path or directory might be wrong.

Remove leading /, i.e."shared/documents/save.dat" and you need to have access_shared action declared
