Debian                                          December 18, 2017                         ZIP_SOURCE_GET_ARGS(3)

       The ZIP_SOURCE_GET_ARGS() macro casts data to a pointer to type.

ZIP_SOURCE_GET_ARGS() fails if:

       [ZIP_ER_INVAL]     len is less than the size of type

ZIP_SOURCE_GET_ARGS() was added in libzip 1.0.
