Not necessarily. What you have probably seen is _POSIX_SSIZE_MAX (which is almost literally what you wrote in your first post), defined in limits.h to be 32767 (2^15 - 1). But that specifies the minimum value that SSIZE_MAX can have and still conform to the POSIX standard. So the actual SSIZE_MAX may well be (and usually is) much bigger, as others have pointed out. > The real issue is whether doing write(2) to a TCP/IP socket bigger > than 2^15 - 1 bytes causes problems.
