How to use a string as param in a function
PostPosted: Wed Apr 09, 2008 1:59 am     Reply with quote
Problem to use a function to transfer a string?

Smal ex. to show the problem.

Code:
void disp_print(st???){
 printf(mydev,"%s",st);
}


void main{
 //test 1 working direct printing
 printf(mydev,"testing"); //working and string is placed in ROM.
 
 //test 2
 disp_print("testing");  //how to do this?

}

Parameter type is "char*".

Notice that for this example to work properly, you have to add :
Code:

#device PASS_STRINGS = IN_RAM

in your code.

Or alternatively:
Code:
void disp_print(char c){
  fputc(c, mydev);
}

void main{
  disp_print("testing");
}
The compiler will automatically create the loop to call disp_print once for each character in the string.
