MEMORY(3TIFF)                                       MEMORY(3TIFF)



NAME
       _TIFFmalloc,    _TIFFrealloc,    _TIFFfree,   _TIFFmemset,
       _TIFFmemcpy,  _TIFFmemcmp,  -  memory   management-related
       functions for use with TIFF files

SYNOPSIS
       #include 

       tdata_t _TIFFmalloc(tsize_t size);
       tdata_t _TIFFrealloc(tdata_t buffer, tsize_t size);
       void _TIFFfree(tdata_t buffer);
       void _TIFFmemset(tdata_t s, int c, tsize_t n);
       void  _TIFFmemcpy(tdata_t dest, const tdata_t src, tsize_t
       n);
       int  _TIFFmemcmp(const  tdata_t  s1,  const  tdata_t   s2,
       tsize_t n);

DESCRIPTION
       These  routines are provided for writing portable software
       that uses libtiff; they hide any memory-management related
       issues, such as dealing with segmented architectures found
       on 16-bit machines.

       _TIFFmalloc and _TIFFrealloc are used to dynamically allo-
       cate and reallocate memory used by libtiff; such as memory
       passed into the I/O  routines.  Memory  allocated  through
       these  interfaces is released back to the system using the
       _TIFFfree routine.

       Memory allocated through one of the above  interfaces  can
       be  set  to  a  known  value  using _TIFFmemset, copied to
       another memory location using _TIFFmemcpy, or compared for
       equality using _TIFFmemcmp.  These routines conform to the
       equivalent ANSI C routines: memset,  memcpy,  and  memcmp,
       repsectively.

DIAGNOSTICS
       None.
