Guess I'll start first by porting these functions, one-at-a-time, from C to PHP:

Blue means "First Cut Done" in this thread/project (update each time a function is ported to PHP)

Code:

extern /* Subroutine */ int calc_barometric_pressure();
extern /* Subroutine */ int calc_deco_ceiling();
extern /* Subroutine */ int onset_of_impermeability();
extern /* Subroutine */ int radius_root_finder();
extern /* Subroutine */ int nuclear_regeneration(), clock_();
extern /* Subroutine */ int vpm_repetitive_algorithm();
extern /* Subroutine */ int gas_loadings_surface_interval();
extern /* Subroutine */ int critical_volume();	    ;
extern /* Subroutine */ int calc_crushing_pressure(), 
                            calc_surface_phase_volume_time(), 
                            decompression_stop();
extern /* Subroutine */ int calc_start_of_deco_zone();
extern /* Subroutine */ int calc_initial_allowable_gradient(), 
                            gas_loadings_ascent_descen();
extern /* Subroutine */ int gas_loadings_constant_depth();
extern /* Subroutine */ int vpm_altitude_dive_algorithm();
extern /* Subroutine */ int calc_max_actual_gradient(), 
                            projected_ascent();

extern /* Subroutine */ doublereal schreiner_equation__();
extern /* Subroutine */ doublereal haldane_equation__();

WARNING: Breathing compressed gas underwater, whether with conventional open-circuit scuba or closed-circuit rebreathers, is a potentially dangerous activity that requires specialized training. Breathing gas mixtures other than air underwater and especially using rebreather technology underwater, are activities which require considerable specialized training and certification. No one should ever attempt these activities without professional training.

VPM decompression algorithm +++for NEO+++

Hi Neo, i have followed your porting of the VPM algorithm to C+. Did you ever finish this exercise? I am playing around with some ARM chips and would love to run the algorithm on them... would you care to share the final results? Thanks for your help. Greetings Carsten

gui_edit_proc

gui_shadow_box_proc(3alleg4)					  Allegro manual				      gui_shadow_box_proc(3alleg4)

NAME

       gui_shadow_box_proc,  gui_ctext_proc,  gui_button_proc,	gui_edit_proc, gui_list_proc, gui_text_list_proc - Hooks to customise the look and
       feel of Allegro dialogs.

SYNOPSIS

       #include <allegro.h>

       extern int (*gui_shadow_box_proc)(int msg, struct DIALOG *d, int c);

       extern int (*gui_ctext_proc)(int msg, struct DIALOG *d, int c);

       extern int (*gui_button_proc)(int msg, struct DIALOG *d, int c);

       extern int (*gui_edit_proc)(int msg, struct DIALOG *d, int c);

       extern int (*gui_list_proc)(int msg, struct DIALOG *d, int c);

       extern int (*gui_text_list_proc)(int msg, struct DIALOG *d, int c);

DESCRIPTION

       If set, these functions will be used by the standard Allegro dialogs.   This  allows  you  to  customise  the  look  and  feel,	much  like
       gui_fg_color and gui_bg_color, but much more flexibly.
