#define APR_DECLARE_OPTIONAL_FN | ( | ret, | |
name, | |||
args | |||
) | typedef ret (APR_OPTIONAL_FN_TYPE(name)) args |
Declare an optional function.
ret | The return type of the function |
name | The name of the function |
args | The function arguments (including brackets) |
Definition at line 50 of file apr_optional.h.
#define APR_OPTIONAL_FN_TYPE | ( | name | ) | apr_OFN_##name##_t |
The type of an optional function.
name | The name of the function |
Definition at line 42 of file apr_optional.h.
#define APR_REGISTER_OPTIONAL_FN | ( | name | ) |
do { \ APR_OPTIONAL_FN_TYPE(name) *apu__opt = name; \ apr_dynamic_fn_register(#name,(apr_opt_fn_t *)apu__opt); \ } while (0)
Register an optional function. This can be later retrieved, type-safely, by name. Like all global functions, the name must be unique. Note that, confusingly but correctly, the function itself can be static!
name | The name of the function |
Definition at line 70 of file apr_optional.h.
#define APR_RETRIEVE_OPTIONAL_FN | ( | name | ) | (APR_OPTIONAL_FN_TYPE(name) *)apr_dynamic_fn_retrieve(#name) |
Retrieve an optional function. Returns NULL if the function is not present.
name | The name of the function |
