NAME

     zip_source_win32w, zip_source_win32w_create — create data source from a Windows Unicode file
     name

LIBRARY

     libzip (-lzip)

SYNOPSIS

     #include <zip.h>

     zip_source_t *
     zip_source_win32w(zip_t *archive, const wchar_t *fname, zip_uint64_t start,
         zip_int64_t len);

     zip_source_t *
     zip_source_win32w_create(const wchar_t *fname, zip_uint64_t start, zip_int64_t len,
         zip_error_t *error);

DESCRIPTION

     The functions zip_source_win32w() and zip_source_win32w_create() create a zip source on
     Windows using a Windows Unicode name.  They open fname and read len bytes from offset start
     from it.  If len is 0 or -1, the whole file (starting from start) is used.

     If the file supports seek, the source can be used to open a zip archive from.

     The file is opened and read when the data from the source is used, usually by zip_close() or
     zip_open_from_source().

RETURN VALUES

     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.

ERRORS

     zip_source_win32w() and zip_source_win32w_create() fail if:

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

     [ZIP_ER_MEMORY]    Required memory could not be allocated.

     [ZIP_ER_OPEN]      Opening fname failed.
