- _TIFFmalloc, \c

- _TIFFfree, \c
- _TIFFmemset, \c

- \- memory management-related functions for use with

- .SH SYNOPSIS
- .B "#include <tiffio.h>"
- .sp
- .BI "tdata_t _TIFFmalloc(tsize_t " size ");"
- .br
- .BI "tdata_t _TIFFrealloc(tdata_t " buffer ", tsize_t " size ");"

- .BI "void _TIFFfree(tdata_t " buffer ");"
- .br
- .BI "void _TIFFmemset(tdata_t " s ", int " c ", tsize_t " n ");"
- .br
- .BI "void _TIFFmemcpy(tdata_t " dest ", const tdata_t " src ", tsize_t " n ");"

- .BI "int _TIFFmemcmp(const tdata_t " s1 ", const tdata_t "s2 ", tsize_t " n ");"
- .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.
- .SH DIAGNOSTICS
- None.
- .SH "SEE ALSO"
- .BR malloc (3),
- .BR memory (3),
- .BR libtiff (3TIFF)
