[pdf-devel] [flyspray] Extend the 64bit numbers implementation with more 32bit number support

[GNU PDF Library]

THIS IS AN AUTOMATED MESSAGE, DO NOT REPLY.

A new Flyspray task has been opened.  Details are below. 

User who did this - Aleksander Morgado (aleksander) 

Attached to Project - GNU PDF Library
Summary - Extend the 64bit numbers implementation with more 32bit number support
Task Type - Planned Task
Category - Basic Types Module
Status - NEXT
Assigned To - 
Operating System - All
Severity - Low
Priority - High
Reported Version - START
Due in Version - BASE-LAYER-0
Due Date - Undecided
Details - The current implementation of the 64bit number built-in support 
(pdf-types.c|h) works mostly with 64bit input/output parameters. The API of 
this module should be extended in order to allow 32bit input/output parameters. 
Please note that the pdf_i64_t should be treated as an opaque type (blackbox) 
from outside the base types module.

New functions:

pdf_i32_t    pdf_i64_to_i32              (const pdf_i64_t)
pdf_status_t pdf_i64_add_i32             (pdf_i64_t *result, const pdf_i64_t 
addend1, const pdf_i32_t addend2);
pdf_status_t pdf_i64_subtraction_i32_min (pdf_i64_t *result, const pdf_i32_t 
minuend, const pdf_i64_t subtrahend);
pdf_status_t pdf_i64_subtraction_i32_sub (pdf_i64_t *result, const pdf_i64_t 
minuend, const pdf_i32_t subtrahend);
pdf_status_t pdf_i64_mult_i32            (pdf_i64_t *result, const pdf_i64_t 
factor_1, const pdf_i32_t factor_2);
pdf_status_t pdf_i64_div_i32_divisor     (pdf_i64_t *dest, const pdf_i64_t 
dividend, const pdf_i32_t divisor);
pdf_status_t pdf_i64_div_i32_dividend    (pdf_i64_t *dest, const pdf_i32_t 
dividend, const pdf_i64_t divisor);
pdf_status_t pdf_i64_mod_i32_divisor     (pdf_i64_t *dest, const pdf_i64_t 
dividend, const pdf_i32_t divisor);
pdf_status_t pdf_i64_mod_i32_dividend    (pdf_i64_t *dest, const pdf_i32_t 
dividend, const pdf_i64_t divisor);
int          pdf_i64_cmp_i32             (const pdf_i64_t number_1, const 
pdf_i32_t number_2);


These new functions should be included in the documentation of the Base Types 
Module.
These new functions should be implemented in pdf-types.c|h
