Posix-2008: BUFSIZ: Size of <stdio.h> buffers. This shall expand to a positive value. C99: BUFSIZ which expands to an integer constant expression that is the size of the buffer used by the setbuf function; In fact, posix-2008 references LINE_MAX because: Frequently, utility writers selected the UNIX system constant BUFSIZ to allocate these buffers; therefore, some utilities were limited to 512 bytes for I/O lines, while others achieved 4 096 bytes or greater. BUFSIZ was already recognized as to small to hold a single line, yet you're saying it's perfectly fine to use as a buffer for binary data? > If in stead of open(2), fopen(3) had been used, the exact same thing > would happen, but using malloc space rather than stack space.
