Units

Units	Description
PJPipe	Exposes a single class that encapsulates an unnamed pipe and can read and write the pipe.
PJPipeFilters	Classes and other types that can filter or format output from pipes.
PJFileHandle	Exposes a single class that assists in manipulating file handles.

Classes

Class	Unit	Description
TPJPipe	PJPipe	This class encapsulates an un-named pipe. It simplifies read and writing such pipes and creating pipes with inheritable handles.
TPJFileHandle	PJFileHandle	This class can create or open files in various access and sharing modes with specified security and provide access to the file handle. It makes it easy to create or open files with inheritable handles.
TPJPipeFilter	PJPipeFilters	Abstract base class for all classes that filter data read from pipes.
TPJAnsiSBCSPipeFilter	PJPipeFilters	Pipe filter that constructs valid ANSI strings from data read from pipe. Strings are also parsed into lines. Only single byte character sets are supported.
TPJUnicodeBMPPipeFilter	PJPipeFilters	Pipe filter that constructs valid Unicode strings from data read from pipe. Strings are also parsed into lines. Only characters from Unicode’s basic multilingual plane are supported.

Other types

Type	Unit	Description
TPJUnicodeTextReadEvent	PJPipeFilters	Type of text read event triggered by classes that read Unicode strings from pipes.
TPJAnsiTextReadEvent	PJPipeFilters	Type of text read event triggered by classes that read Ansi strings from pipes.
