.SH DESCRIPTION
.sp
These routines are provided for writing portable software that uses
\fBlibtiff\fP; they hide any memory\-management related issues, such as
dealing with segmented architectures found on 16\-bit machines.
.sp
\fI\%_TIFFmalloc()\fP and \fI\%_TIFFrealloc()\fP are used to dynamically
allocate and reallocate memory used by \fBlibtiff\fP; such as memory
passed into the I/O routines. Memory allocated through these interfaces is
released back to the system using the \fI\%_TIFFfree()\fP routine.
.sp
Memory allocated through one of the above interfaces can be set to a known
value using \fI\%_TIFFmemset()\fP, copied to another memory location using
\fI\%_TIFFmemcpy()\fP, or compared for equality using \fI\%_TIFFmemcmp()\fP\&.
These routines conform to the equivalent C routines:
\fBmemset()\fP, \fBmemcpy()\fP, \fBmemcmp()\fP, respectively.
.sp
\fI\%_TIFFCheckMalloc()\fP and \fI\%_TIFFCheckRealloc()\fP are checking for
integer overflow before calling \fI\%_TIFFmalloc()\fP and \fI\%_TIFFrealloc()\fP,
respectively.
.SH DIAGNOSTICS
.sp
None.
