IV43100: SETBUFFER()/SETVBUF() IGNORES USER SUPPLIED BUFFER

APAR status

• Closed as fixed if next.

Error description

• "Technical Reference: Base Operating System and
  Extensions,
  Volume 2" specifies that in the case a user supplies a
  buffer to the setbuffer()/setvbuf() calls that is not a
  NULL pointer, the buffer supplied by the user will be
  used instead of an automatically created one.  The actual
  behavior of the setbuffer()/setvbuf() call is that it
  uses an automatically created buffer even if the user
  supplies their own.
  
  
  Quoting the documentation:
  
  "If the Buffer parameter is not a null character pointer,
  the array it points to is used for buffering."
  
  and
  
  "The character array Buffer, whose size is determined by
  the Size parameter, is used instead of an automatically
  allocated buffer."
  
  The setbuffer() call appears to be included only for
  BSD compatibility purposes.  The setvbuf() call appears
  to conform to the ANSI C standard, however it's actual
  behavior conflicts with its documented behaviour.
