Description
THandleStream enables applications to read from and write to communications resources identified by a handle. {{#multireplace:System.Classes.TFileStream|H21=!|H25=%|H28=(|H29=)|H2A=*|H2B=+|H2F=/|H3C=<|H3D==|H3E=>|H5B=[|H5D=]|H5E=^|H7C=|}} inherits from {{#multireplace:System.Classes.THandleStream|H21=!|H25=%|H28=(|H29=)|H2A=*|H2B=+|H2F=/|H3C=<|H3D==|H3E=>|H5B=[|H5D=]|H5E=^|H7C=|}}. All content below this line refers to {{#multireplace:System.Classes.THandleStream|H21=!|H25=%|H28=(|H29=)|H2A=*|H2B=+|H2F=/|H3C=<|H3D==|H3E=>|H5B=[|H5D=]|H5E=^|H7C=|}}.
THandleStream enables applications to read from and write to communications resources identified by a handle.
Use THandleStream to access files, sockets, named pipes, mailslots, or other communications resources that provide a handle when opened. For example, the FileOpen function provides a handle for a file on disk. THandleStream allows applications to use a uniform stream interface when performing I/O using a handle.
To avoid the overhead of managing file handles, use TFileStream to work with disk files.
