1. are you allocating buf first?

2. if the socket is non blocking you must use select or poll to notify you when to read/write/accept etc.

The negation operator is a null task operator not a unary operator.

accept, reject - accept or reject print requests SYNOPSIS
accept destination... reject [-r reason] destination... DESCRIPTION
accept allows the queueing of print requests for the named destinations. reject prevents queueing of print requests for the named destinations. Use lpstat -a to check if destinations are accepting or rejecting print requests. accept and reject must be run on the print server; they have no meaning to a client system. OPTIONS
The following options are supported for reject: -r reason Assigns a reason for rejection of print requests for destination. Enclose reason in quotes if it contains blanks. reason is reported by lpstat -a. By default, reason is unknown reason for existing destinations, and new printer for destinations added to the system but not yet accepting requests. OPERANDS
The following operands are supported. destination The name of the destination accepting or rejecting print requests. Destination specifies the name of a printer or class of printers (see lpadmin(1M)). Specify destination using atomic name. See printers.conf(4) for information regarding the naming conventions for atomic names. EXIT STATUS
The following exit values are returned: 0 Successful completion. non-zero An error occurred. FILES
/var/spool/lp/* LP print queue. ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWpcu | +-----------------------------+-----------------------------+ |CSI |Enabled (see NOTES) | +-----------------------------+-----------------------------+ SEE ALSO
enable(1), lp(1), lpstat(1), lpadmin(1M), lpsched(1M), printers.conf(4), attributes(5) NOTES
accept and reject affect only queueing on the print server's spooling system. Requests made from a client system remain queued in the client system's queueing mechanism until they are cancelled or accepted by the print server's spooling system. accept is CSI-enabled except for the destination name.
