how do i write the contents of an unsigned char vector to a file.
i get some output but its not the contents of the file.
1 2 3 4 5 6 7 8

vector<unsigned char> bufferType;
ofstream textout (pathname.c_str(), ios::out | ios::binary);
{
textout.write((const char*)&bufferType[0], bufferType.size());
}
textout.close();

please help thx.
Works fine.
#include <vector>
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22
|
#include <iostream>
#include <fstream>
#include <string>
using namespace std;
int main()
{
vector<unsigned char> bufferType;
bufferType.push_back('e');
bufferType.push_back('P');
bufferType.push_back('R');
bufferType.push_back('f');
string pathname("output.bin");
ofstream textout(pathname.c_str(), ios::out | ios::binary);
textout.write((const char*)&bufferType[0], bufferType.size());
textout.close();
}

The file generated contains the following in hex:
which is clearly the ASCII values of
ePRf ( e = 0x65, P = 0x50, R = 0x52, f=0x66)
If I open the file as a text file, the contents are clear in text:
some other function was overwriting the contents of my vector and it was giving me bad results
thanks for your help.
