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