zip_fdopen —
open zip archive using open file descriptor
libzip (-lzip)
#include
<zip.h>
zip_t *
zip_fdopen(
int
fd,
int
flags,
int
*errorp);
The zip archive specified by the open file descriptor
fd is opened and a pointer to a
struct zip, used to manipulate the archive,
is returned. In contrast to
zip_open(3), using
zip_fdopen the archive can only be opened
in read-only mode. The
fd argument may not be
used any longer after calling
zip_fdopen.
The
flags are specified by
or'ing the following
values, or 0 for none of them.
-
-
ZIP_CHECKCONS- Perform additional stricter consistency checks on the archive, and error
if they fail.
If an error occurs and
errorp is
non-NULL, it will
be set to the corresponding error code.
Upon successful completion
zip_fdopen()
returns a
struct zip pointer, and
fd should not be used any longer, nor passed
to
close(2). Otherwise,
NULL is returned and
*errorp is set to indicate the error. In the
error case,
fd remains unchanged.
The file specified by
fd is prepared for use by
libzip(3) unless:
-
-
- [
ZIP_ER_INCONS]
- Inconsistencies were found in the file specified by
path. This error is often caused by
specifying
ZIP_CHECKCONS but can also
happen without it.
-
-
- [
ZIP_ER_INVAL]
- The flags argument is invalid. Not all
zip_open(3) flags are
allowed for
zip_fdopen, see
DESCRIPTION.
-
-
- [
ZIP_ER_MEMORY]
- Required memory could not be allocated.
-
-
- [
ZIP_ER_NOZIP]
- The file specified by fd is not a zip
archive.
-
-
- [
ZIP_ER_OPEN]
- The file specified by fd could not be
prepared for use by
libzip(3).
-
-
- [
ZIP_ER_READ]
- A read error occurred; see errno for
details.
-
-
- [
ZIP_ER_SEEK]
- The file specified by fd does not allow
seeks.
