How can I read an entire text file to a buffer?

Using Win32 functions CreateFile and ReadFile. I don't want to specify a static size for the char [ ] buffer as it will depend on the size of the file. I need a buffer I can pour the entire file into. If somebody can point me to a sample, then that would help. Cheers

    Wow, it has been forever since I've fooled with Win32. However, being a C and Java programmer, I have run into the same problem and offer this technique in pseudo code. There should be some function to get the "sizeof" the file. With the size, allocate the buffer size, then read the data into the buffer. You should be able to embed the whole whole thing into one line: putInAllocatedMemory(readFile(allocateMemory(sizeof(filename)))). Or, if you would like to make it more readable, you can break it down into a couple of lines. Your compiler should optimize it. I hope this helps.

    The Perl language excels in text manipulation. PERL (Practical Extraction and Reporting Language). You might want to consider that... $file = "yourfile.txt"; @buffer = ""; open(IN_FILE, "<$file") or die("Error: Could not open $file"); @buffer = ; close (IN_FILE); print @buffer;
