A very good question. Of cause there are limits how much data can be
packed into a single sentence. 

First, "if" testing was only used allowing an alternative
command-route if the target environment is not supported.

To ventilate your bungalow: 

if(t3d_environment_IS_SUN_WINDOW())  /* returns always: yes = 1, no =
0 , ret < 0 = error code */ 
{
    t3d_open_SUN_WINDOW();  /* contains full list of #ifdef
environment-> action choices*/
			    /* #ifdef MY_BUNGALOW #endif  #ifdef
SIBERIAN_DATCHA #endif */
}

else if(t3d_environment_IS_ROOF_APERTURE())
{
    t3d_open_ROOF_WINDOW();  /* contains full list of #ifdef
environment-> action choices*/
			     /* #ifdef LEXUS #endif   #ifdef
MY_BUNGALOW #endif          */
}
else
{
    t3d_write_CONSOLE("environment stinks");
}

Your last question requires a bit different approach. The X-parameter
is used for giving a function additional values; using warargs. Thus

#include<stdio.h>
#include<stdlib.h>

int main(void)
{
   if(t3d_environment_IS_ROOF_WINDOW())   
   {
      t3d_open_ROOF_WINDOW_PERCENTAGEXXX("45");  
   }
   else 
   {
      fprintf(stderr,"could not open the roof window by 45
percentages");
   }
   return(EXIT_SUCCESS);
}


Still in doubt, please send more challenges. Naturally I'd prefer to
answer questions commonly needed in real-life computing tasks, like:

t3d_convert_file_Rfile_HTML2TEXT
t3d_create_BEEP_HZXXX_DURATIONXXX
t3d_measure_file_Rbarray_OWNER
