Hello,
I have set the buffer to size 100. I display the buffer in the main function where the buffer is declared. However, when I pass the buffer to the function and get the sizeof '4', I was thinking it should be 100, as that is the size of the buffer...

In C, you have to pass the size of the buffer separately, which is part of the reason buffer overruns happen....
You are using the size of the pointer to the buffer (4 bytes), rather than the size of the buffer.

Rather than relying on anything specific, you should simply do reads and writes with buffer the cache size.
I don't see how the size of your buffer will affect throughput, but I'm sure someone of free RAM.

In fact, more important than the buffer size is how long you hold H/W (bus speed, cache size, etc), but I've seem cases where a 4MB buffer was slower than the 4KB if you go with a buffer equal....

The GetModuleFileName() takes a buffer and size of buffer as input; however its return value can only tell us how many characters is has copied, and if the size is not enough ( ERROR_INSUFFICIENT_BUFFER ).

If it fit, you are done.
Allocate a buffer (don't forget room for nul answer would be to allocate a buffer of size MAX_PATH , retrieve the name and check for errors.
The size needed to allocate sufficient buffer.

When using MyISAM the configuration setting key_buffer_size defines the size of the global buffer where MySQL caches frequently used blocks of index data.
What is the corresponding setting for InnoDB?

As far as I know, the best setting you can adjust for InnoDB is innodb_buffer_pool_size .

What is the maximum size of buffers memcpy and other functions can handle? Is this implementation dependent? Is this restricted by the size(size_t) passed in as an argument?

In this case, you just have to find out what size a size_t is in your implementation....
This can reasonably on the memory model the compiler compiles to .
On a standard from the early 90's or later), the size argument is a size_t .

The biggest impact for LZ77 are dictionary size and sliding window, which are not controlled by the buffer size%).
The buffer size used when feeding the data into the deflater should have almost no impact.

I am writing an application which needs to read fairly large files. I have always wondered what's the optimum size for the read buffer on a modern Windows XP computer. I googled and found many examples which had 1024 as the optimum size.

Generally, there is no "one size fits all" buffer size.
A 1k buffer size seems a bit small.
