DESCRIPTION
The
libewf_get_version
()
function is used to retrieve the library version.
The
libewf_get_flags_*
()
functions are used to get the values of the flags for read and/or write.
The
libewf_check_file_signature
()
and
libewf_check_file_signature_wide
()
functions are used to test if the EWF file signature is present within a
certain filename.
The
libewf_glob
()
and
libewf_glob_wide
()
functions glob filenames using the
filename and the format
according to the EWF segment file naming schema. If the
format is known the filename should contain the base
of the filename otherwise the function will try to determine the format
based on the extension.
The
libewf_handle_signal_abort
()
function signals the handle to aborts it current activity.
The
libewf_handle_open
(),
libewf_handle_open_wide
(),
libewf_handle_close
(),
libewf_handle_read_buffer
(),
libewf_handle_read_random
(),
libewf_handle_write_buffer
(),
libewf_handle_write_random
(),
libewf_handle_seek_offset
()
functions can be used to open, seek in, read from, write to and close a set
of EWF files.
The
libewf_handle_write_finalize
()
function needs to be called after writing a set of EWF files without knowing
the input size upfront, e.g. reading from a pipe.
libewf_handle_write_finalize
() will the necessary
correction to the set of EWF files.
The
libewf_handle_prepare_read_chunk
(),
libewf_handle_read_chunk
()
functions can be used to read chunks to a set of EWF files.
The
libewf_handle_prepare_write_chunk
(),
libewf_handle_write_chunk
()
functions can be used to write chunks to a set of EWF files.
The
libewf_handle_get_*
()
functions can be used to retrieve information from the
handle. This information is read from a set of EWF
files when libewf_handle_open
() or
libewf_handle_open_wide
() is used.
The
libewf_handle_set_*
()
functions can be used to set information in the
handle. This information is written to a set of EWF
files when
libewf_handle_write_buffer
()
is used.
The
libewf_handle_append_acquiry_error
()
function can be used to append an acquiry error (a read error during
acquiry) to be written into a set of EWF files.
The
libewf_handle_append_checksum_error
()
function can be used to append an Adler-32 checksum error (a validation
error in a chunk in a set of EWF files) to be set in the handle.
The
libewf_handle_append_session
()
function can be used to append a session to be written into a set of EWF
files. Note that the only the start offset is stored in a set of EWF files.
Libewf ignores the number of sectors on write and determines the session
sizes using the available session and media information on read.
The
libewf_handle_copy_*
()
functions copy information from the source_handle to
the destination_handle.
The
libewf_notify_set_verbose
(),
libewf_notify_set_stream
()
functions can be used to direct the warning, verbose and debug output from
the library.
RETURN VALUES
Most of the functions return NULL or -1 on error, dependent on the return type. For the actual return values refer to libewf.h
To determine the cause of an error pass a reference to libewf_error_t *error = NULL. libewf will create an error object that must be freed with the libewf_error_free function. If the error reference is NULL libewf will not create an error object.
ENVIRONMENT
None
FILES
None
NOTES
libewf supports both UTF-8 and UTF-16 encoded strings except for
filenames. Some platforms like WINAPI require wide character support for
Unicode filenames. To compile libewf with wide character support use
./configure --enable-wide-character-type=yes or pass
the definition _UNICODE
or UNICODE
to the compiler (i.e. in case of Microsoft Visual Studio (MSVS) C++).
To have other code to determine if libewf was compiled with wide
character support it defines
LIBEWF_HAVE_WIDE_CHARACTER_TYPE
in libewf/features.h.
The header in a set of EWF files contains an extended ASCII string
using the codepage of the system it was created on. The function
libewf_handle_set_header_codepage
allows one to set the required codepage for reading and writing. The default
codepage is ASCII and replaces all extended characters to the Unicode
replacement character (U+fffd) when reading and the ASCII substitute
character (0x1a) when writing.
The header2 contains UTF-16 little endian stream and the xheader and xhash contain a UTF-8 stream without or with byte order mark (as of version 20080903).
libewf allows one to be compiled with chained IO support using libbfio. libewf will automatically detect if a compatible version of libbfio is available.
To have other code to determine if libewf was compiled with
libbfio support it defines LIBEWF_HAVE_BFIO
in libewf/features.h.
