NAME¶
zip_source_file
,
zip_source_file_create
—
create data source from a file
LIBRARY¶
libzip (-lzip)
SYNOPSIS¶
#include
<zip.h>
zip_source_t *
zip_source_file
(zip_t
*archive, const char
*fname, zip_uint64_t
start, zip_int64_t
len);
zip_source_t *
zip_source_file_create
(const
char *fname, zip_uint64_t
start, zip_int64_t
len, zip_error_t
*error);
DESCRIPTION¶
The functions
zip_source_file
()
and
zip_source_file_create
()
create a zip source from a file. 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_file
() and
zip_source_file_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.
