示例1: openLogFile
bool openLogFile(const std::string &complete_file_with_path, std::ofstream &outstream) {
std::ios_base::openmode mode = std::ios_base::out; // for clarity: it's really overkill since it's an ofstream
mode |= std::ios_base::trunc;
outstream.open(complete_file_with_path, mode);
if (!outstream.is_open()) {
std::ostringstream ss_error;
ss_error << "FILE ERROR: could not open log file:[" << complete_file_with_path << "]";
ss_error << "\n\t\t std::ios_base state = " << outstream.rdstate();
std::cerr << ss_error.str().c_str() << std::endl;
outstream.close();
return false;
}
return true;
