Extract an array of eight‐byte IEEE doubles from this stream.

Synopsis

Declared in <bslx_byteinstream.h>

ByteInStream&
getArrayFloat64(
    double* variables,
    int numVariables);

Description

Assign to the specified variables the consecutive eight‐byte IEEE double‐precision floating‐point numbers (in host byte order) comprised of each of the specified numVariables eight‐byte sequences of this stream at the current cursor location (in network byte order), update the cursor location, and return a reference to this stream. If this stream is initially invalid, this operation has no effect. If this function otherwise fails to extract a valid value, this stream is marked invalid and the value of variables is undefined. The behavior is undefined unless 0 <= numVariables and variables has sufficient capacity.

Return Value

a reference to this stream

Parameters

Name

Description

variables

destination array for the extracted values

numVariables

number of eight‐byte floating‐point values to extract
