cannot save file...
Hello! I have a problem:
I compile some function, which must save file:
=====================
// prog.cpp
void save_file(){
FILE *fs = fopen("file.txt", "w");
if(!fs) cerr<< "cannot save";
fprintf(fs, "This is a text file.");
fclose(fs)
}
=====================
If i compile it from command command line
...root]# g++ prog.cpp
...root]# ./a.out
It starts and saves file normally.
But if i run this function in a programm from as CGI
programm(in Apache) - it doesn't save file! Says "cannot save"...
Maybe it s a problem with permissions? I have neard, that
Apache executes everything in "cgi-bin" as a user "nobody" -
maybe this is a reason? If it is, how can I cnange the permissions
and to what? Is there a function in C++ for permissions changing?
