Function attribute_pre_init

pub unsafe extern "C" fn attribute_pre_init<T: PluginAPI<E>, E: PluginError + 'static>(
    plugin_data: *const PluginData,
    id: size_t,
    pre_init: *mut c_char,
) -> c_int

Indicates whether an attribute may be set before initialization.

This function accepts a pointer to a c_char. If the char is ATTRIBUTE_PRE_INIT_FALSE after the function returns and it returns a value of PLUGIN_OK, then the attribute that corresponds to the provided ID may not be set before plugin initialization. If the char is any value other than 0 and the function returns PLUGIN_OK, then the plugin may be set before initialization.

If the function does not return PLUGIN_OK, then the value stored at pre_init will not be modified.

Safety

This function is unsafe because it dereferences raw pointers.

Arguments

• plugin_data - A pointer to a PluginData struct
• id - The id of the attribute
• pre_init - A value that determines whether the attribute’s value may be set before the plugin is initialized
