Make a file pointer read/write to an in-memory location

Question

I can make a file pointer write to a file with fopen(). But can I make a file pointer that will make it so calling functions such as fputc or fprintf will write to a pointer

Answer 1

With a memory mapped file. This is platform specific so you'll need to find the information about creating mem-mapped files on your target system(s). I believe the posix version is mmap. At any rate, searching for "memory mapped file" on google should turn up a bunch of help.
