How to create C++ istringstream from a char array with null(0) characters?
- by Morpheus
I have a char array which contains null characters at random locations. I tried to create an iStringStream using this array (encodedData_arr) as below,
I use this iStringStream to insert binary data(imagedata of Iplimage) to a MySQL database blob field(using MySQL Connector/C++'s setBlob(istream *is) ) it only stores the characters upto the first null character.
Is there a way to create an iStringStream using a char array with null characters?
unsigned char *encodedData_arr = new unsigned char[data_vector_uchar->size()];
// Assign the data of vector<unsigned char> to the encodedData_arr
for (int i = 0; i < vec_size; ++i)
{
cout<< data_vector_uchar->at(i)<< " : "<< encodedData_arr[i]<<endl;
}
// Here the content of the encodedData_arr is same as the data_vector_uchar
// So char array is initializing fine.
istream *is = new istringstream((char*)encodedData_arr, istringstream::in || istringstream::binary);
prepStmt_insertImage->setBlob(1, is);
// Here only part of the data is stored in the database blob field (Upto the first null character)
