I am trying to read data faster with read and fread. They both fail to read data from my console window when I specify any value greater than 32767 for the buffer size parameter. Don't know why 
How do I find the maximum possible value for that parameter? Can anybody help me with this? I searched internet for two hours but found no solution or explanation to this.
