ZIP_SOURCE_WIN32HANDLE(3) Library Functions Manual ZIP_SOURCE_WIN32HANDLE(3)

zip_source_win32handle, zip_source_win32handle_create
create data source from a Windows file handle

libzip (-lzip)

#include <zip.h>

zip_source_t *
zip_source_win32handle(zip_t *archive, HANDLE h, zip_uint64_t start, zip_int64_t len);

zip_source_t *
zip_source_win32handle_create(HANDLE h, zip_uint64_t start, zip_int64_t len, zip_error_t *error);

The functions zip_source_win32handle() and zip_source_win32handle_create() create a zip source from a Windows file handle. 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().

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.

zip_source_w32handle() and zip_source_w32handle_create() fail if:
[]
fname, start, or len are invalid.
[]
Required memory could not be allocated.
[]
Opening fname failed.
