}

For other char arrays from client:

int Client::sanitizeCharArray(char* inArray, char* outData, int maxLength)
{
	int length = strnlen(inArray,maxLength);
	strncpy(outData,inArray,length);
	outData[length] = '\0';
	return length;
}

example:


char targetName[64];
int targetLength = sanitizeCharArray(c->name, (char*)targetName, 64);
