PIO_READ_DOUBLES(3)

EXPERIMENTAL_FUNC
pio_read_doubles - Read double float data from a channel object, trapping NaNs.

SYNOPSIS
#include <karma_pio.h>

uaddr pio_read_doubles

(Channel channel, uaddr num_values, double *data, uaddr *num_nan)

DESCRIPTION
This routine will read many double precision floating point numbers from a channel object and will optionally trap IEEE Not-A-Number (NaN) values. Trapped NaNs are converted to the TOOBIG value.

channel
    The channel object.

num_values
    The number of values to read.

data
    The data will be written here. This will be written in host natural format. The data will be converted from IEEE network format prior to writing.

num_nan
    The number of NaN values found will be written here. If this is NULL then NaN values are not trapped.

RETURN VALUE
The number of values read and converted.

Multi-threading Level
Unsafe.
