Alexei Podtelezhnikov 1a4c18f7cb Align `char_next` return types.
This is mostly cosmetic because FT_UInt and FT_UInt32 are likely identical.

* src/sfnt/ttcmap.c, src/cff/cffcmap.c, src/psaux/t1cmap.c,
src/psnames/psmodule.c, include/freetype/internal/service/svpcsmap.h,
src/pfr/pfrcmap.c, src/winfonts/winfnt.c (*_char_next): return FT_UInt.

Alexei Podtelezhnikov 6139f2b647 [bdf, pfr, psnames] Accelarate charmap searches.
The binary searches within charmaps can be accelerated because they
often contain dense continuous blocks of character codes. Within such
blocks, you can predict matches based on misses.  This method has been
deployed in `bdf` since 0f122fef34; we only refactor it there.  We now
use it in `pfr` and `psnames`, which speeds up the unicode charmap
access by about 50% in PFR and Type 1 fonts.

* src/bdf/bdfdrivr.c (bdf_cmap_char_{index,next}): Refactor.
* src/pfr/pfrcmap.c (pfr_cmap_char_{index,next}): Predict `mid` based
on the mismatch distance.
* src/psnames/psmodule.c (ps_unicodes_char_{index,next}): Ditto.

David Turner e13391333f Make macros for header file names optional.
We no longer have to take care of the 8.3 file name limit; this
allows us (a) to introduce longer, meaningful file names, and (b) to
avoid macro names in `#include' lines altogether since some
compilers (most notably Visual C++) doesn't support this properly.

*/*: Replace

   #include FOO_H

with

   #include <freetype/foo.h>

or something similar.  Also update the documentation.

Werner Lemberg 9ac9060df0 [GSoC] src/*.*: Convert block comments to `light' style.
This monster commit was created by applying Nikhil's scripts
`docconverter.py' and `markify.py' to all C header and source files,
followed up by minor manual clean-up.

No change in functionality, of course.

Jarkko Pöyry 96341dc378 [cff, pfr, psaux, winfonts] Fix Savannah bug #43676.
Don't cast cmap init function pointers to an incompatible type.

Without this patch, the number of parameters between declaration and
the real signature differs.  Calling such a function results in
undefined behavior.

  ISO/IEC 9899:TC3 (Committee Draft September 7, 2007)
    6.5.2.2 Function calls
      9 If the function is defined with a type that is not
        compatible with the type (of the expression) pointed to by
        the expression that denotes the called function, the
        behavior is undefined.

On certain platforms (c -> js with emscripten) this causes
termination of execution or invalid calls because in the emscripten
implementation, function pointers of different types are stored in
different pointer arrays.  Incorrect pointer type here results in
indexing of an incorrect array.

Werner Lemberg e8ed2d621e Another round of cppcheck nitpicks.
The call was (from the top-level of the FreeType tree):

  cppcheck --force \
           --enable=all \
           -I /usr/include \
           -I /usr/local/include \
           -I /usr/lib/gcc/i586-suse-linux/4.7/include \
           -I include \
           -I include/freetype \
           -I include/freetype/config \
           -I include/freetype/internal \
           -DFT2_BUILD_LIBRARY \
           . &> cppcheck.log

using cppcheck git commit f7e93f99.

Note that cppcheck still can't handle `#include FOO' (with `FOO' a
macro).

Werner Lemberg e3c9301581 */*: Use FT_Err_Ok only.
This is a purely mechanical conversion.
2013-03-14 11:21:17 +01:00
Werner Lemberg 059bc335ce */*: Use `FT_THROW'.
This is essentially a mechanical conversion, adding inclusion of
`FT_INTERNAL_DEBUG_H' where necessary, and providing the macros for
stand-alone compiling modes of the rasterizer modules.

To convert the remaining occurrences of FT_Err_XXX and friends it is
necessary to rewrite the code.  Note, however, that it doesn't harm
if some cases are not handled since FT_THROW is a no-op.
