Debian                                            June 30, 2023                              ZIP_SOURCE_FILEP(3)

       The  functions  zip_source_filep()  and zip_source_filep_create() create a zip source from a file stream.
       They read len bytes from offset start from the open file stream file.   For  a  description  of  the  len
       argument, see zip_source_file(3).

       If the file stream supports seeking, the source can be used to open a read-only zip archive from.

       The file stream is closed when the source is being freed, usually by zip_close(3).

zip_source_filep() fails if:

       [ZIP_ER_INVAL]     file, start, or len are invalid.

       [ZIP_ER_MEMORY]    Required memory could not be allocated.

zip_source_filep() and zip_source_filep_create() were added in libzip 1.0.

       ZIP_LENGTH_TO_END and ZIP_LENGTH_UNCHECKED were added in libzip 1.10.1.

       Upon  successful  completion,  the created source is returned.  Otherwise, NULL is returned and the error
       code in archive or error is set to indicate the error.
