  51 .SH DESCRIPTION
  52 These routines are provided for writing portable software that uses
  53 .IR libtiff ;
  54 they hide any memory-management related issues, such as dealing with segmented
  55 architectures found on 16-bit machines.
  56 .PP
  57 .I _TIFFmalloc
  58 and
  59 .I _TIFFrealloc
  60 are used to dynamically allocate and reallocate memory used by
  61 .IR libtiff ;
  62 such as memory passed into the I/O routines. Memory allocated through these
  63 interfaces is released back to the system using the
  64 .I _TIFFfree
  65 routine.
  66 .PP
  67 Memory allocated through one of the above interfaces can be set to a known
  68 value using
  69 .IR _TIFFmemset ,
  70 copied to another memory location using
  71 .IR _TIFFmemcpy ,
  72 or compared for equality using
  73 .IR _TIFFmemcmp .
  74 These routines conform to the equivalent
  75 .SM ANSI
  76 C routines:
  77 .IR memset ,
  78 .IR memcpy ,
  79 and
  80 .IR memcmp ,
  81 repsectively.
  82 .SH DIAGNOSTICS
  83 None.
