FILE* interface to NSString or NSData?

[Michael Hopkins]

Hi all

We want to convert a C library that reads from and writes to binary FILE*
descriptors using fread() & fwrite() to do the same thing but accessing e.g.
NSString or NSData objects instead.

Is there some accepted (cross-platform safe) way of doing this using
Foundation/GNUstep-base?  We have the whole compatible subset of Cocoa
Foundation and GNUstep-base available if a solution needs other classes to
be involved.

Thx - links appreciated and feel free to CC me
