Produces ANSI prototypes from K&R function definitions. This should help to ease the transition from K&R to ANSI.
.-nogenproto-----------------. >>- -q--+-genproto--+--------------+-+------------------------->< '-=--parmnames-'
Using -qgenproto without parmnames will cause prototypes to be generated without parameter names. Parameter names are included in the prototype when parmnames is specified.
For the following function, foo.c:
foo(a,b,c) float a; int *b; int c;
specifying
xlc -c -qgenproto foo.c
produces
int foo(double, int*, int);
The parameter names are dropped. On the other hand, specifying
xlc -c -qgenproto=parmnames foo.c
produces
int foo(double a, int* b, int c);
In this case the parameter names are kept.
Note that float a is represented as double or double a in the prototype, since ANSI states that all narrow-type arguments (such as chars, shorts, and floats) are widened before they are passed to K&R functions.
