-qgenproto (C only)
Category
Pragma equivalent
None.
Purpose
Produces prototype declarations from K&R function definitions or function definitions with empty parentheses, and displays them to standard output.
The compiler accepts and compiles K&R function definitions or definitions with a function declarator with empty parentheses; however, these function definitions are considered by the C standard to be obsolete (the compiler will diagnose them if you enable the -qinfo=obs option). When -qgenproto is in effect, the compiler generates the corresponding prototype declarations and displays them to standard output. You can use this option to help you identify obsolete function definitions and automatically obtain equivalent prototypes.
Syntax
.-nogenproto-----------------. >>- -q--+-genproto--+--------------+-+------------------------->< '-=--parmnames-'
Defaults
-qnogenproto
Parameters
- parmnames
- Parameter names are included in the prototype. If you do not specify this suboption, parameter names will not be included in the prototype.
Predefined macros
None.
Examples
Compiling with - qgenproto for the following function
definitions:
int foo(a, b) // K&R function
int a, b;
{
}
int faa(int i) { } // prototyped function
main() { // missing void parameter
}int foo(int, int);
int main(void);Specifying -qgenproto=parmnames produces:
int foo(int a, int b);
int main(void);
