Function libmpv_sys::mpv_get_property

pub unsafe extern "C" fn mpv_get_property(
    ctx: *mut mpv_handle, 
    name: *const c_char, 
    format: mpv_format, 
    data: *mut c_void
) -> c_int

Read the value of the given property.

If the format doesn't match with the internal format of the property, access usually will fail with MPV_ERROR_PROPERTY_FORMAT. In some cases, the data is automatically converted and access succeeds. For example, MPV_FORMAT_INT64 is always converted to MPV_FORMAT_DOUBLE, and access using MPV_FORMAT_STRING usually invokes a string formatter.

@param name The property name. @param format see enum mpv_format. @param[out] data Pointer to the variable holding the option value. On success, the variable will be set to a copy of the option value. For formats that require dynamic memory allocation, you can free the value with mpv_free() (strings) or mpv_free_node_contents() (MPV_FORMAT_NODE). @return error code
