NAME

Genezzo::RawIO - Genezzo Raw IO

SYNOPSIS Additional file read and write routines for Genezzo.

DESCRIPTION sysread and syswrite are wrapped by genread and genwrite so raw devices (via rawread and rawwrite) may optionally be used.

ARGUMENTS

FUNCTIONS

setUseRaw BOOL

Set to 1 to enable aligned I/O for raw devices.  Set to 0 
to disable.

getUseRaw

Returns 1 if aligned I/O for raw devices is enabled.  Returns 0 
if disabled.

genread FILEHANDLE, SCALAR, LENGTH

Performs read identical to sysread, except uses aligned buffer 
suitable for raw I/O if setUseRaw was previously called.

genwrite FILEHANDLE, SCALAR, LENGTH

Performs write identical to syswrite, except uses aligned buffer 
suitable for raw I/O if setUseRaw was previously called.

EXPORT

getUseRaw, setUseRaw, genread, genwrite

LIMITATIONS

Relies on Perl Inline::C module.  Code may gracefully compile to 
empty stubs on non-raw (non-Linux) platforms, but this has not 
been thoroughly tested.
