17 /* _GL_UNUSED_PARAMETER is a marker that can be appended to function parameter
18 declarations for parameters that are not used. This helps to reduce
19 warnings, such as from GCC -Wunused-parameter. The syntax is as follows:
20 type param _GL_UNUSED_PARAMETER
21 or more generally
22 param_decl _GL_UNUSED_PARAMETER
23 For example:
24 int param _GL_UNUSED_PARAMETER
25 int *(*param)(void) _GL_UNUSED_PARAMETER
26 Other possible, but obscure and discouraged syntaxes:
27 int _GL_UNUSED_PARAMETER *(*param)(void)
28 _GL_UNUSED_PARAMETER int *(*param)(void)
