type Config 

type Config struct {

	CC                  string // The configured C compiler, filled by NewConfig.
	FS                  fs.FS

	IncludePaths        []string
	PragmaHandler       func([]Token) error
	Predefined          string // The predefined macros from CC, filled by NewConfig.
	SysIncludePaths     []string

	// Default cc.Kinds for types the type checker cannot work without. Used only
	// when the type is not defined already but needed. Must be an integer type or
	// zero (= cc.InvalidKind). The last fallback is C int.
	DefaultSizeT    Kind
	DefaultPtrdiffT Kind
	DefaultWcharT   Kind

	// EvalAllMacros enables attempt to assign a value to all object-like, constant macros.
	EvalAllMacros bool
	// Header disables type checking of function bodies.
	Header bool
	// GCC compatibility: enums with no negative values will have unsigned type.
	UnsignedEnums bool
	// contains filtered or unexported fields
}

Config configures the preprocessor, parser and type checker.

Search paths listed in IncludePaths and SysIncludePaths are used to resolve #include "foo.h" and #include <foo.h> preprocessing directives respectively. A special search path "@" or "" is interpreted as 'the same directory as where the file with the #include "foo" directive is'.

If FS is nil, os.Open is used to open named files.

func NewConfig 

func NewConfig(goos, goarch string, opts ...string) (r *Config, err error)

NewConfig returns the system C compiler configuration, or an error, if any. The function will look for the compiler first in the environment variable CC, then it'll try other options. Usually that means looking for the "cc" and "gcc" binary, in that order.

Additional arguments (flags) in opts are passed to the system C compiler unchanged. For example, the _REENTRANT preprocessor macro is defined when the -pthread flag is present. The set of recognized keywords is adjusted to emulate gcc, see: 

https://gcc.gnu.org/onlinedocs/gcc/Alternate-Keywords.html#Alternate-Keywords

Execution of NewConfig is expensive, caching the results is recommended wherever possible.

If goos or goarch are empty, the current OS and architecture are used.

func (*Config) AdjustLongDouble added in v4.5.0 

func (c *Config) AdjustLongDouble() error

AdjustLongDouble will force C long double to have the same size as Go float64 and C complex long double as Go complex128.

		int b;
		int c;
		int d;
	} e;
	int f;
} g;

A postfix expression node for 'g.a' will have the field 'a' attached, with no parent. A postfix expression node for 'g.c' will have the field 'c' attached, with parent field 'e'.

func (*Field) ParentField added in v4.4.0
