ZIP_FILE_GET_EXTERNAL_AT (3) Library Functions Manual ZIP_FILE_GET_EXTERNAL_AT (3)
NAME
zip_file_get_external_attributes — get external attributes for file in zip
LIBRARY
libzip (-lzip)
SYNOPSIS
#include <zip.h>
int
zip_file_get_external_attributes ( zip_t *archive , zip_uint64_t index , zip_flags_t flags , zip_uint8_t *opsys , zip_uint32_t *attributes );
DESCRIPTION
The zip_file_get_external_attributes () function returns the operating system and external attributes for the file at position index in the zip archive. The external attributes usually contain the operating system-specific file permissions. If flags is set to ZIP_FL_UNCHANGED, the original unchanged values are returned. If opsys or attributes are NULL, they are not filled in.
The following operating systems are defined by the zip specification:
ZIP_OPSYS_ACORN_RISC
ZIP_OPSYS_ALTERNATE_MVS
ZIP_OPSYS_AMIGA
ZIP_OPSYS_ATARI_ST
ZIP_OPSYS_BEOS
ZIP_OPSYS_CPM
ZIP_OPSYS_DOS
ZIP_OPSYS_MACINTOSH
ZIP_OPSYS_MVS
ZIP_OPSYS_OPENVMS
ZIP_OPSYS_OS_2
ZIP_OPSYS_OS_400
ZIP_OPSYS_OS_X
ZIP_OPSYS_TANDEM
ZIP_OPSYS_UNIX
ZIP_OPSYS_VFAT
ZIP_OPSYS_VM_CMS
ZIP_OPSYS_VSE
ZIP_OPSYS_WINDOWS_NTFS (uncommon, use ZIP_OPSYS_DOS instead)
ZIP_OPSYS_Z_SYSTEM
The defines above follow the PKWARE Inc. Appnote; please note that the InfoZIP Appnote has a slightly different mapping.
RETURN VALUES
Upon successful completion, 0 is returned. In case of an error, -1 is returned and the error code in archive is set to indicate the error.
EXAMPLES
The following code can be used to expand attributes if the operating system is ZIP_OPSYS_DOS.
#include <sys/stat.h>
#define
FA_RDONLY 0x01 // FILE_ATTRIBUTE_READONLY
#define FA_DIREC 0x10 // FILE_ATTRIBUTE_DIRECTORY
static mode_t
_zip_dos_attr2mode(zip_uint32_t attr)
{
mode_t m = S_IRUSR | S_IRGRP | S_IROTH;
if (0 == (attr & FA_RDONLY))
m |= S_IWUSR | S_IWGRP | S_IWOTH;
if (attr &
FA_DIREC)
m = (S_IFDIR | (m & ˜S_IFMT)) | S_IXUSR | S_IXGRP |
S_IXOTH;
return m;
}
ERRORS
zip_file_get_external_attributes () fails if:
[ZIP_ER_INVAL]
index is not a valid file index in archive .
