LIBRARY

Streaming Archive Library (libarchive, -larchive)  

SYNOPSIS

In archive.h Ft int Fn archive_read_support_filter_all struct archive * Ft int Fn archive_read_support_filter_bzip2 struct archive * Ft int Fn archive_read_support_filter_compress struct archive * Ft int Fn archive_read_support_filter_grzip struct archive * Ft int Fn archive_read_support_filter_gzip struct archive * Ft int Fn archive_read_support_filter_lrzip struct archive * Ft int Fn archive_read_support_filter_lz4 struct archive * Ft int Fn archive_read_support_filter_lzma struct archive * Ft int Fn archive_read_support_filter_lzop struct archive * Ft int Fn archive_read_support_filter_none struct archive * Ft int Fn archive_read_support_filter_rpm struct archive * Ft int Fn archive_read_support_filter_uu struct archive * Ft int Fn archive_read_support_filter_xz struct archive * Ft int Fo archive_read_support_filter_program Fa struct archive * Fa const char *cmd Fc Ft int Fo archive_read_support_filter_program_signature Fa struct archive * Fa const char *cmd Fa const void *signature Fa size_t signature_length Fc  

DESCRIPTION

Fn archive_read_support_filter_bzip2 , Fn archive_read_support_filter_compress , Fn archive_read_support_filter_grzip , Fn archive_read_support_filter_gzip , Fn archive_read_support_filter_lrzip , Fn archive_read_support_filter_lz4 , Fn archive_read_support_filter_lzma , Fn archive_read_support_filter_lzop , Fn archive_read_support_filter_none , Fn archive_read_support_filter_rpm , Fn archive_read_support_filter_uu , Fn archive_read_support_filter_xz
Enables auto-detection code and decompression support for the specified compression. These functions may fall back on external programs if an appropriate library was not available at build time. Decompression using an external program is usually slower than decompression through built-in libraries. Note that ``none'' is always enabled by default.
Fn archive_read_support_filter_all
Enables all available decompression filters.
Fn archive_read_support_filter_program
Data is fed through the specified external program before being dearchived. Note that this disables automatic detection of the compression format, so it makes no sense to specify this in conjunction with any other decompression option.
Fn archive_read_support_filter_program_signature
This feeds data through the specified external program but only if the initial bytes of the data match the specified signature value.

 

RETURN VALUES

These functions return ARCHIVE_OK if the compression is fully supported, ARCHIVE_WARN if the compression is supported only through an external program.

Fn archive_read_support_filter_none always succeeds.  

ERRORS

Detailed error codes and textual descriptions are available from the Fn archive_errno and Fn archive_error_string functions.
