When user has a standard account (not administrator), he/she doesn't have rights to create a file in the Directory /Applications/. I try to create a file with the help of function authopen. This code doesn't work:

FILE *pFile = popen("/usr/libexec/authopen -stdoutpipe sys.openfile.readwritecreate./applications/tolea.txt", "w");
if(pFile == NULL){
NSLog(@"NOT Create");
}else{
NSLog(@"Create");
char *data = "Create";
pwrite(data, 1, size(data), pFile);
}
pclose(pFile);

How would be the correct way to do?

Besides what everyone else said, lose the -stdoutpipe and use -w or -a (depending on your needs). -stdoutpipe uses SCM_RIGHTS, which is rather subtle and tricky to use.
