I am slowly ploughing my way through the list of links to on-line tutorials you provided to newbies. I for one am grateful for such a comprehensive list, so first of all thank you for that.
What i cannot seem to find, is information on C++ libraries:

Hi,
this is my first experience with Solaris.
For work, I must configured an applicacion (oracle EPM, this include Datadirect odbc drivers) in solaris.
Additionally, we must connect to Sybase IQ Database (I installed odbc drivers to do this).
The problem is, I can't get those two odbc... (1 Reply)

ieee1284_wait_data
IEEE1284_DATA(3) Functions IEEE1284_DATA(3)NAME
ieee1284_read_data, ieee1284_write_data, ieee1284_data_dir, ieee1284_wait_data - control the data lines
SYNOPSIS
#include <ieee1284.h>
int ieee1284_read_data(struct parport *port);
void ieee1284_write_data(struct parport *port, unsigned char dt);
int ieee1284_data_dir(struct parport *port, int reverse);
int ieee1284_wait_data(struct parport *port, unsigned char mask, unsigned char val, struct timeval *timeout);
DESCRIPTION
These functions manipulate the data lines of the parallel port associated with port (which must have been claimed using ieee1284_claim(3)).
The lines are represented by an 8-bit number (one line per bit) and a direction. The data lines are driven as a group; they may be all
host-driven (forward direction) or not (reverse direction). When the peripheral is driving them the host must not.
For ieee1284_data_dir the reverse parameter should be zero to turn the data line drivers on and non-zero to turn them off. Some port types
may be unable to switch off the data line drivers.
Setting the data lines may have side effects on some port types (for example, some Amiga ports pulse nStrobe).
ieee1284_wait_data waits, up until the timeout, for the data bits specified in mask to have the corresponding values in val.
RETURN VALUE
ieee1284_read_data returns the 8-bit number representing the data lines unless it is not possible to return such a value with this port
type, in which case it returns an error code. Possible error codes:
E1284_NOTAVAIL
Bi-directional data lines are not available on this system.
E1284_INVALIDPORT
The port parameter is invalid (perhaps it has not been claimed, for instance).
E1284_SYS
There was an error at the operating system level, and errno has been set accordingly.
E1284_TIMEDOUT
The timeout has elapsed.
Whereas ieee1284_read_data may return E1284_NOTAVAIL on its first invocation on the port, if it does not do so then it cannot until
ieee1284_close is called for that port.
