-.TH Tcl_CreateFileHandler 3 8.0 Tcl "Tcl Library Procedures"
-.BS
-.SH NAME
-Tcl_CreateFileHandler, Tcl_DeleteFileHandler \- associate procedure callbacks with files or devices (Unix only)
-.SH SYNOPSIS
-.nf
-\fB#include <tcl.h>\fR
-.sp
-\fBTcl_CreateFileHandler\fR(\fIfd, mask, proc, clientData\fR)
-.sp
-\fBTcl_DeleteFileHandler\fR(\fIfd\fR)
-.SH ARGUMENTS
-.AS Tcl_FileProc clientData
-.AP int fd in
-Unix file descriptor for an open file or device.
-.AP int mask in
-Conditions under which \fIproc\fR should be called:
-OR-ed combination of \fBTCL_READABLE\fR, \fBTCL_WRITABLE\fR,
-and \fBTCL_EXCEPTION\fR.  May be set to 0 to temporarily disable
-a handler.
-.AP Tcl_FileProc *proc in
-Procedure to invoke whenever the file or device indicated
-by \fIfile\fR meets the conditions specified by \fImask\fR.
-.AP ClientData clientData in
-Arbitrary one-word value to pass to \fIproc\fR.
-.BE
-
-.SH DESCRIPTION
-.PP
-\fBTcl_CreateFileHandler\fR arranges for \fIproc\fR to be
-invoked in the future whenever I/O becomes possible on a file
-or an exceptional condition exists for the file.  The file
-is indicated by \fIfd\fR, and the conditions of interest
-are indicated by \fImask\fR.  For example, if \fImask\fR
-is \fBTCL_READABLE\fR, \fIproc\fR will be called when
-the file is readable.
-The callback to \fIproc\fR is made by \fBTcl_DoOneEvent\fR, so
-\fBTcl_CreateFileHandler\fR is only useful in programs that dispatch
-events through \fBTcl_DoOneEvent\fR or through Tcl commands such
-as \fBvwait\fR.
-.PP
-\fIProc\fR should have arguments and result that match the
-type \fBTcl_FileProc\fR:
-.CS
-typedef void Tcl_FileProc(
-        ClientData \fIclientData\fR,
-        int \fImask\fR);
-.CE
-The \fIclientData\fR parameter to \fIproc\fR is a copy
-of the \fIclientData\fR
-argument given to \fBTcl_CreateFileHandler\fR when the callback
-was created.  Typically, \fIclientData\fR points to a data
-structure containing application-specific information about
-the file.  \fIMask\fR is an integer mask indicating which
-of the requested conditions actually exists for the file;  it
-will contain a subset of the bits in the \fImask\fR argument
-to \fBTcl_CreateFileHandler\fR.
-.PP
-.PP
-There may exist only one handler for a given file at a given time.
-If \fBTcl_CreateFileHandler\fR is called when a handler already
-exists for \fIfd\fR, then the new callback replaces the information
-that was previously recorded.
-.PP
-\fBTcl_DeleteFileHandler\fR may be called to delete the
-file handler for \fIfd\fR;  if no handler exists for the
-file given by \fIfd\fR then the procedure has no effect.
-.PP
-The purpose of file handlers is to enable an application to respond to
-events while waiting for files to become ready for I/O.  For this to work
-correctly, the application may need to use non-blocking I/O operations on
-the files for which handlers are declared.  Otherwise the application may
-block if it reads or writes too much data; while waiting for the I/O to
-complete the application will not be able to service other events. Use
-\fBTcl_SetChannelOption\fR with \fB\-blocking\fR to set the channel into
-blocking or nonblocking mode as required.
-.PP
-Note that these interfaces are only supported by the Unix
-implementation of the Tcl notifier.
