Thanks for reply. What i mean by slow was that when u want get file from ftp server and save it to your localhost or such operations works very slow, and i think it is from why i use "system" function in c, if i use other low level OS function, it could be faster such as Curl or something else.

Hello, I have finished writing ftp client in c/c++ using system funtion to get/put ftp commands for example:

int FTPGet(char *asFtpSite, char *asFtpUser, char *asFtpPasswd, char* asRemoteDir,
char *asRemoteFile, char *asLocalFile, char *asLogFile)
{
char lsFtpCommand[4096];

sprintf(lsFtpCommand,
"export LANG=en_US\n"
"ftp -i -v -n >%s <<EOJ\n"
"open %s\n"
"user %s %s\n"
"ascii\n"
"cd %s\n"
"get %s %s\n"
"bye\n"
"EOJ\n",
asLogFile,
asFtpSite,asFtpUser,asFtpPasswd,
asRemoteDir,
asRemoteFile,asLocalFile);

system(lsFtpCommand);
return 0;

}

It works fine, but very slow, I found out it is why because i use "system" function, What i want to ask from u, Is there any other method to make it faster? I am told that there is a ftp library for C, which is cURL, somebody has ever tried it? or Is There any other ftp library which works faster? My platform is IBM AIX unix. Thanks in advance

I took such a large memory on purpose to test bad allocation exception, i figure out how to do that,here is my final code, this works,

# include # include # include #include struct tree_node
{
std::list<tree_node*> leaf;
char data;
short IsEndPoint;
};

void MyHandler()
{
std::cout << "MyHandler Called... " << std::endl;
throw std::bad_alloc();
}

int main()
{
std::set_new_handler( MyHandler );

char\* ch;
try
{
	for( unsigned long Idx( 0 ); Idx < 0xffffffff; ++Idx )
	{
		new tree\_node\[10000\];
		printf("id: %d \\r",Idx);
	}
}
catch( const std::bad\_alloc& e )
{
	std::cout << e.what() << std::endl;
}

std::cin.get();
return 0;

}
