次のような構成ファイルを読み込もうとしています:
rawfile=input.raw
encfile=encoded.enc
decfile=decoded.raw
width=512
height=512
rle=1
quantfile=matrix.txt
logfile=log.txt
この機能を持つ:
void Compression::readConfigFile(char * input)
{
string lineBuf;
string optionBuf;
std::ifstream confFile(input);
if ( confFile.is_open() )
{
while ( getline( confFile, lineBuf ) )
{
optionBuf = "rawfile=";
if ( ( ( int )lineBuf.find(optionBuf) ) != -1 )
{
lineBuf.erase( 0, optionBuf.length() );
this->rawfile = lineBuf.c_str();
}
optionBuf = "encfile=";
if ( ( ( int )lineBuf.find(optionBuf) ) != -1 )
{
lineBuf.erase( 0, optionBuf.length() );
this->encfile = lineBuf.c_str();
}
optionBuf = "decfile=";
if ( ( ( int )lineBuf.find(optionBuf) ) != -1 )
{
lineBuf.erase( 0, optionBuf.length() );
this->encfile = lineBuf.c_str();
}
optionBuf = "width=";
if ( ( ( int )lineBuf.find(optionBuf) ) != -1 )
{
lineBuf.erase( 0, optionBuf.length() );
this->width = atoi( lineBuf.c_str() );
}
optionBuf = "height=";
if ( ( ( int )lineBuf.find(optionBuf) ) != -1 )
{
lineBuf.erase( 0, optionBuf.length() );
this->height = atoi( lineBuf.c_str() );
}
optionBuf = "rle=";
if ( ( ( int )lineBuf.find(optionBuf) ) != -1 )
{
lineBuf.erase( 0, optionBuf.length() );
this->rle = atoi( lineBuf.c_str() );
}
optionBuf = "quantfile=";
if ( ( ( int )lineBuf.find(optionBuf) ) != -1 )
{
lineBuf.erase( 0, optionBuf.length());
this->matrix = lineBuf.c_str();
}
optionBuf = "logfile=";
if ( ( ( int )lineBuf.find(optionBuf) ) != -1 )
{
lineBuf.erase( 0, optionBuf.length() );
this->logfile = lineBuf.c_str();
}
confFile.close();
}
}
else
cout << "Can't open file: " << input << endl;
}
しかし、うまくいきません。私のintは0または大きな数字です。私の文字列はまだ空です。
誰か助けてくれませんか?
敬具、
