Error when generating from a certain syntax structure

[KristofferC]

I have some code that structurally looks like:

typedef struct s {
} s;

int (*s_f(const struct s* n))(struct s*);

When trying to generate this I hit #354 because:

cursor = CLCursor (Clang.CLFunctionDecl) s_f(const struct s *)
args = Clang.CLCursor[CLCursor (Clang.CLParmDecl) , CLCursor (Clang.CLParmDecl) n]
types = Clang.CLType[CLType (Clang.CLPointer) , CLType (Clang.CLInvalid) ]

in

Clang.jl/src/generator/system_deps.jl

Lines 11 to 12 in 2c9230d

	args = get_function_args(cursor)
	types = CLType[getArgType(getCursorType(cursor), i - 1) for i in 1:length(args)]

@KristofferC I can't parse this C code int (*s_f(const struct s* n))(struct s*);

https://cdecl.org also gives a syntax error.

You could remove the parameter name n, then it gives:

declare s_f as function (pointer to const struct s) returning pointer to function (pointer to struct s) returning int

it is used here https://github.com/dankamongmen/notcurses/blob/4f91a717d1e37df95080847e0eeb0cd6ece9cf10/include/notcurses/notcurses.h#L1373-L1374.

Gcc seems to be ok with it:

❯ cat test.h 
typedef struct s {
} s;

int (*s_f(const struct s* n))(struct s*);

❯ gcc -fsyntax-only test.h
