BlockWrite Writes Block(s) to Untyped File
BlockWrite(var OutFile : file; Storage : <type>; NumBlocks : Integer); [TP]
Writes out some number of blocks from any type of variable or data
structure into an untyped file. You must call Assign and Rewrite (or
Reset, followed by a call to Seek) before calling BlockWrite.
OutFile Untyped file; must have been previously opened using
Assign and Rewrite, Append, or Truncate; if you are
using Seek, can also have been opened with Reset.
Storage A variable of <type>; should be at least as large as
NumBlocks * block size.
<type> Any data type except a file type.
NumBlocks The number of blocks to be written out.
Block size is by default 128 bytes; however, it is possible to set the
block size to another value when you call Reset or Rewrite.
-------------------------------- Example ---------------------------------
BlockWrite(UFile,Buffer,4); { write 512 bytes }
