ZIP_SOURCE_WINDOW_CREATE(3) Introduction to Library Functions
NAME
zip_source_window_create - create zip data source overlay
LIBRARY
libzip (-lzip)
SYNOPSIS
#include <zip.h> zip_source_t * zip_source_window_create(
zip_source_t *source,
zip_uint64_t start,
zip_int64_t len,
zip_error_t *error);
DESCRIPTION
The
zip_source_window_create() function create a zip source from an
underlying zip source, restricting access to a particular window
starting at byte
start and having size
len. If
len is -1, the window
spans to the end of the underlying source.
zip_source_window() and
zip_source_window_create() don't take ownership
of
source. The caller is responsible for freeing it. (This is
different to other layered sources.)
RETURN VALUES
Upon successful completion, the created source is returned. Otherwise,
NULL is returned and the error code in
error is set to indicate the
error.
ERRORS
zip_source_window_create() fails if:
[ZIP_ER_INVAL]
src is NULL; there is an integer overflow adding
start and
len; or
len is less than -1.
[ZIP_ER_MEMORY] Required memory could not be allocated.
