Re: [pdf-devel] Assigning a 64-bit value to pdf_i64_t

[jemarch]

Hi Aleks.

   We have a function that can be used to initialize a pdf_i64_t with a 
   pdf_i32_t:

   void
   pdf_i64_assign_quick (pdf_i64_t *bignum,
                          const pdf_i32_t value,
                          pdf_status_t *p_status);

   But, what if I am in a OS with built-in 64-bit support (like I guess we 
   all are) and I want to assign a 64-bit value (coming from system 
   functions for example) into a pdf_i64_t?

   Well, we can also use `pdf_i64_assign_quick' for that, as in those types 
   of OS that function will just be a macro, which doesn't take care of 
   type sizes. Note that we can't use "=" for that, as it would break our 
   built-in 64-bit support.

   But, I don't think it's clear from the API document point of view, as it 
   seems that only 32-bit integers are allowed. How can we explain this in 
   the document? Just with a note saying... "hey, you can also use a 64-bit 
   value in this function instead of a pdf_i32_t"... or what?

I will drop notes about the existence of the macros in the reference
manual.

   And BTW, didn't we talk about adding an option to configure in order to 
   force the use of our built-in 64-bit support?

I just commited a patch in the trunk adding a new configure option for
that purpose: --enable-bignum-forcing
