.SH DESCRIPTION
|
|
|
|
|
These routines are provided for writing portable software that uses
|
|
|
|
|
.IR libtiff ;
|
|
|
|
|
they hide any memory-management related issues, such as dealing with segmented
|
|
|
|
|
architectures found on 16-bit machines.
|
|
|
|
|
.PP
|
|
|
|
|
.I _TIFFmalloc
|
|
|
|
|
and
|
|
|
|
|
.I _TIFFrealloc
|
|
|
|
|
are used to dynamically allocate and reallocate memory used by
|
|
|
|
|
.IR libtiff ;
|
|
|
|
|
such as memory passed into the I/O routines. Memory allocated through these
|
|
|
|
|
interfaces is released back to the system using the
|
|
|
|
|
.I _TIFFfree
|
|
|
|
|
routine.
|
|
|
|
|
.PP
|
|
|
|
|
Memory allocated through one of the above interfaces can be set to a known
|
|
|
|
|
value using
|
|
|
|
|
.IR _TIFFmemset ,
|
|
|
|
|
copied to another memory location using
|
|
|
|
|
.IR _TIFFmemcpy ,
|
|
|
|
|
or compared for equality using
|
|
|
|
|
.IR _TIFFmemcmp .
|
|
|
|
|
These routines conform to the equivalent
|
|
|
|
|
.SM ANSI
|
|
|
|
|
C routines:
|
|
|
|
|
.IR memset ,
|
|
|
|
|
.IR memcpy ,
|
|
|
|
|
and
|
|
|
|
|
.IR memcmp ,
|
|
|
|
|
repsectively.
