Buffer getValue()
syntax: |
buffer.getValue([valueSize[, valueType]]) |
where: |
valueSize - a positive number describing the number of bytes to be used and defaults to 1. The following are acceptable values: 1, 2, 3, 4, 8, and 10
valueType - One of the following types: "signed", "unsigned", or "float". The default type is: "signed."

|
description: |
This call is similar to the Buffer putValue() function, except that it gets a value instead of puts a value.
|
see: |
Buffer putValue(), Buffer[] Array
|
example: |
/* To explicitly put a value at a specific location while preserving the cursor location, do something similar to the following. */
// Save the old cursor location var oldCursor = foo.cursor; // Set to new location foo.cursor = 20; // Get goo at offset 20 bar = foo.getValue(goo); // Restore cursor location foo.cursor = oldCursor
//Please see Buffer.putValue // for a more complete description. |
