Hello roottalk, Could some one help me with a question on checking the status of a file. Is there a way using a ROOT macro to test if a file can be written to? Eg. in C I would do the check FILE *fPtr; if((fPtr = fopen("file.dat","w")) == NULL) printf("can't open file.dat"); I can't seem to find a function with a return value that I can test in the same way as the fopen function. Is there a "file->CanWriteTo()" type of check? I am using ROOT 2.22/09 on Linux.
