then this is unnecessary. The #cgo noescape directive may be used to tell
the compiler that no Go pointers escape via the named C function.
If the noescape directive is used and the C function does not handle the
pointer safely, the program may crash or see memory corruption.

For example:

	// #cgo noescape cFunctionName

	}
	return s
}

// ProcessCgoDirectives processes the import C preamble:
//  1. discards all #cgo CFLAGS, LDFLAGS, nocallback and noescape directives,
//     so they don't make their way into _cgo_export.h.
//  2. parse the nocallback and noescape directives.
func (f *File) ProcessCgoDirectives() {
	linesIn := strings.Split(f.Preamble, "\n")
	linesOut := make([]string, 0, len(linesIn))
