Thread: Pass function to function

Compile hangs up at calc_run_time1 call for calc_vap_abv.
Error message is: 'argument' undeclared (first use in this function).

Full code is lengthy so these are pertinent snippets.
The pointer types are arrays, except for the calc_vap_abv function. The calc_vap_abv function solves the array elements that the calc_runtime1 function then uses.

Can you tell from snippets what I am doing wrong?
Thx



Definitions

Code:

double calc_vap_abv(
    int index, 
    double *pot_l_abv, 
    double *pot_v_abv, 
    double *pot_r_abv, 
    double c_riser1, 
    double c_riser2, 
    double init_reflux)

Code:

double calc_run_time1(
    int index, 
    double *pot_l_vol, 
    double *pot_l_abv, 
    double *thp_l_vol, 
    double *thp_l_abv, 
    double *pot_r_abv,                   
    double p_kw1, 
    double riser_time, 
    double c_riser1,
    double *runtime, 
    double pot_abv_dec,
    double (*calc_vap_abv)(int index, double *pot_l_abv, double *pot_v_abv, 
                  double *pot_r_abv, double c_riser1, double c_riser2, double init_reflux))

runtime call

Code:

 calc_run_time1(
    index, 
    pot_l_vol, 
    pot_l_abv, 
    thp_l_vol, 
    thp_l_abv, 
    pot_r_abv, 
    p_kw1, 
    riser_time, 
    c_riser1, 
    run_time, 
    pot_abv_dec, 
    calc_vap_abv);

calc vap abv call inside runtime function

Code:

calc_vap_abv(
    index, 
    pot_l_abv, 
    pot_v_abv, 
    pot_r_abv, 
    c_riser1, 
    c_riser2, 
    init_reflux);

There are no parameters or variables called argument in what you posted.

Is this in scope, or it's prototype already exists, before you try to pass it as a parameter in calc_run_time1 ?

wanted to add the program is a work in progress from a spreadsheet that models a two stage distillation.

I assume you know about the many many unused variables and will fix that later.
About this function:

Code:

double calc_run_time1(
    int index,
    double *pot_l_vol,
    double *pot_l_abv,
    double *thp_l_vol,
    double *thp_l_abv,
    double *pot_r_abv,
    double p_kw1,
    double riser_time,
    double c_riser1,
    double *runtime,
    double pot_abv_dec,
    double (*calc_vap_abv)(int, double*, double*, double*, double, double, double))

Note that pot_v_abv (an array declared in main) is not passed into this function at all.
It is only mentioned as the name of a parameter to a function that is being passed in.
I removed those names above as they are not needed.
Those names are only for programmer information and are totally ignored by the compiler.
You need to pass pot_v_abv in as a separate parameter if you want to pass it to that function.
I'm assuming all of your troubles are similar to this.
