I need to get the size of the stdin buffer, (or any FILE buffer), but can''t find any information on how, is it even possiable?

I don''t know if this works with stdin (or other redirections and pipes) but it works with normal files:

  FILE *File = ...;long Filesize;fseek(File,SEEK_END,0);Filesize = ftell(File);fseek(File,SEEK_SET,0);

IIRC all stdio buffers are BUFSIZ bytes large initially. BUFSIZ is declared in stdio.h
You can change the buffering for a FILE* file with the functions setbuf() and setvbuf()
