RTL Routines, LIB$, LIB$WAIT

The Wait a Specified Period of Time routine places the current
process into hibernation for the number of seconds specified in
its argument.
Format
LIB$WAIT seconds [,flags] [,float-type]
OpenVMS usage:cond_value
type: longword (unsigned)
access: write only
mechanism: by value
seconds
OpenVMS usage:floating_point
type: F_floating
access: read only
mechanism: by reference
The number of seconds to wait. The seconds argument contains the
address of an F-floating number that is this number.
The value is rounded to the nearest hundredth-second before use.
Seconds must be between 0.0 and 100,000.0.
flags
OpenVMS usage:mask_longword
type: longword (unsigned)
access: read only
mechanism: by reference
Control flags. The flags argument is the address of a longword
integer that contains the control flags. The following flag is
defined:
Bit Value Description
0 LIB$K_NOWAKE LIB$WAIT will not wake in the case of an
interrupt.
This is an optional argument. If omitted, the default is 0, and
LIB$WAIT will wake in the case of an interrupt.
float-type
OpenVMS usage:longword-unsigned
type: longword (unsigned)
access: read only
mechanism: by reference
Float type. The float-type argument is the address of a longword
integer that determines the floating-point type of the seconds
argument. Use one of the following symbols:
Symbol Value Floating-Point Type
LIB$K_VAX_F 0 F_floating
LIB$K_VAX_D 1 D_floating
LIB$K_VAX_G 2 G_floating
LIB$K_VAX_H 3 H_floating
LIB$K_IEEE_S 4 IEEE_S_floating
LIB$K_IEEE_T 5 IEEE_T_floating
This is an optional argument. If omitted, the default is F_
floating. F_floating is the required float-type when LIB$WAIT
is called from a module written in a language that prototypes
functions.
