Re: [pdf-devel] pdf-fsys-file size function and pdf_size_t

[jemarch]

Hi Scott.

   pdf_fsys_file_get_size(...)
   pdf_fsys_file_set_size(...)
   pdf_fsys_file_set_pos(...)
   pdf_fsys_file_get_pos(...)

   all convey size information with pdf_size_t.

   size_t will be 32-bits on some systems (4GB size limit)
   I regularly work with 1GB PDF files - 4GB can't be far off...

   Shouldn't we convey all file size information (offsets and sizes)

   with pdf_i64_t on all systems?  (I.e. shouldn't we handle these

   offsets/sizes as pdf_i64_t instead of pdf_size_t?)

The Adobe SDK manages this problem by providing a set of 64-bit
specific functions in platforms supporting it.

Instead we are following a simpler strategy: we assume that the people
wanting to manipulate 4GB PDF files will be working in a 64 bits
architecture.

If you think that strategy to be unreasonable, please say so: it is
better to manage this kind of issues in an early stage :)
