"tmpfile()" implementation in contrib/libtests/pngstest.c "tmpfile()" implementation in contrib/libtests/pngstest.c
Fixed NO_STDIO build of pngunknown.c to skip calling png_init_io()
if there is no stdio.h support.
Added an API and a number of assist macros to allow an application
that uses the simplified API write to bypass stdio and write
directly to memory.
Added some warnings (png.h) and some check code to detect *possible*
overflow in the ROW_STRIDE and simplified image SIZE macros. This
disallows image width/height/format that *might* overflow. This is
a quiet API change that limits in-memory image size (uncompressed) to
less than 4GByte and image row size (stride) to less than 2GByte.
Revised Simplified API to use system appropriate types. This is
an API change for 1.7, albeit a quiet one; it may produce compiler
warnings but should not result in errors, unless warnings are treated
as errors. On 64-bit systems it widens the results of the various
PNG_IMAGE_ macros that return size values (component counts, byte sizes)
to 64 bits. It also changes the row_stride parameter, which is the
pointer difference between adjacent rows of the image buffer, to
the ANSI-C90 defined type ptrdiff_t. The existing (1.6.22) checks for
overflow are preserved but now accomodate images that require more than
32 bits of address space when size_t/ptrdiff_t are 64 bit types.
