strtok and '\r\n'

[mickey]

Hello,
IMHO there's an error in the first version of your code ( the second strtok); this is my version of code (probably is what you wanted); anyway it doens't work because at //*, line takes "nullptr" and this first loop end...any hints?

vector<double> v;
	vector< vector<double> > doubleVector;
	char* line;
	line = strtok(_buffer, "\r\n");
	while ( line != NULL ) {
		cout << line << endl;
		char* value = strtok(line, ",");
			while ( value != NULL) {
				cout << value << endl;
				v.push_back( strtod(value, NULL) );
				value = strtok(NULL, ",");			
			}		
		doubleVector.push_back(v);
		v.clear();
		line = strtok(NULL, "\r\n");	//*	<------ problem
	}

vector<double> v;
	vector< vector<double> > doubleVector;
	char* line;
	line = strtok(_buffer, "\r\n");
	while ( line != NULL ) {
		cout << line << endl;
		char* value = strtok(line, ",");
			while ( value != NULL) {
				cout << value << endl;
				v.push_back( strtod(value, NULL) );
				value = strtok(NULL, ",");			
			}		
		doubleVector.push_back(v);
		v.clear();
		line = strtok(NULL, "\r\n");	//*	<------ problem
	}
