About functions

• removefunctiondefinition argument is not a user function pointer

  
  
  

• you cannot redefine or undefine an active function

  
  
  

• function <functionname> not yet defined when you call a function declared but not defined.

  
  
  

• computed function is not a function when you attempt to call through a function pointer an illegal function, checked only if you have defined a RUNTIMECHECK cpp name. Here is an example generating this error message:

  
  
  

• ? arguments for <functionname>, ? required when you call a function through a pointer with a bad number of arguments, checked only if you have defined a RUNTIMECHECK cpp name. Example:

  ((void(*)()) error)(); /* 0 arguments for error, 1 required */

• not enough number of argument for <functionname> (? given) when you call a built-in function with a variable number of arguments with not enough arguments.

  { printf("the missing argument is : %s"); }
