syswrite
syswrite filehandle, scalar, length, [offset]
Writes length bytes of
data from variable scalar to the
specified filehandle. The function
returns the number of bytes actually written, or the undefined
value on error. You should be prepared to handle the problems that
standard I/O normally handles for you, such as partial writes. The
offset, if specified, says where in the
string to start writing from, in case you’re using the string as a
buffer, for instance, or need to recover from a partial
write.
Do not mix calls to print
(or write) and syswrite on the same filehandle unless
you really know what you’re doing.
