dlpi_set_timeout(3DLPI)
NAME
dlpi_set_timeout - set DLPI handle timeout interval
SYNOPSIS
cc [ flag ... ] file ... -ldlpi [ library ... ]
#include
int dlpi_set_timeout(dlpi_handle_t dh, int sec);
DESCRIPTION
The dlpi_set_timeout() function sets the timeout interval to
sec seconds on DLPI handle dh. This timeout is used by libdlpi(3LIB) functions that require explicit acknowledgment from the associated DLPI link, and bounds the number of seconds that a function will wait for an acknowledgmentbefore returning DLPI_ETIMEDOUT. Except for
dlpi_recv(3DLPI), which has a timeout argument, any function
that is documented to return DLPI_ETIMEDOUT can take up to
the timeout interval to complete. Callers that do not require an upper bound on timeouts arestrongly encouraged to never call dlpi_set_timeout(), and
allow libdlpi to use its default timeout value. The defaulttimeout value is intended to ensure that DLPI_ETIMEDOUT will
only be returned if the DLPI link has truly become unrespon-
sive. The default timeout value is intended to ensure thatDLPI_ETIMEDOUT will be returned only if the DLPI link has
truly become unresponsive. Callers that do require an explicit upper bound can specifythat value at any time by calling dlpi_set_timeout(). How-
ever, note that values less than 5 seconds may trigger spurious failures on certain DLPI links and systems under high load, and thus are discouraged. Attempts to set the timeout value to less than 1 second will fail.If sec is set to DLPI_DEF_TIMEOUT, the default timeout value
is restored.RETURN VALUES
Upon success, DLPI_SUCCESS is returned. Otherwise, a DLPI
error value is returned.ERRORS
DLPI_EINHANDLE Invalid DLPI handle
