NAME
       memchan - C API for creating memory channels

SYNOPSIS
       package require Tcl

       package require memchan

       Tcl_Channel Memchan_CreateMemoryChannel (Tcl_Interp *interp, int initialSize)

       Tcl_Channel Memchan_CreateFifoChannel (Tcl_Interp *interp)

       void Memchan_CreateFifo2Channel (Tcl_Interp *interp, Tcl_Channel *aPtr, Tcl_Channel *bPtr)

       Tcl_Channel Memchan_CreateNullChannel (Tcl_Interp *interp)

       Tcl_Channel Memchan_CreateZeroChannel (Tcl_Interp *interp)

       Tcl_Channel Memchan_CreateRandomChannel (Tcl_Interp *interp)

DESCRIPTION
       The  memchan  package provides a C API for use by third-party extension writers. This is exposed by a
       Tcl stubs library table to reduce version dependency as is available for Tcl itself.

COMMAND
       Tcl_Channel Memchan_CreateMemoryChannel (Tcl_Interp *interp, int initialSize)

       Tcl_Channel Memchan_CreateFifoChannel (Tcl_Interp *interp)

       void Memchan_CreateFifo2Channel (Tcl_Interp *interp, Tcl_Channel *aPtr, Tcl_Channel *bPtr)

       Tcl_Channel Memchan_CreateNullChannel (Tcl_Interp *interp)

       Tcl_Channel Memchan_CreateZeroChannel (Tcl_Interp *interp)

       Tcl_Channel Memchan_CreateRandomChannel (Tcl_Interp *interp)


       Each of these functions creates an returns a channel exactly as described in the  Tcl  command  pages
       for  each  of  the  memchan  commands. The Tcl commands internally call these functions to create the
       channels.

       The memchan channel accepts an initialSize argument to permit pre-allocating space for  the  internal
       buffer. Normally this may be set to 0.

       The fifo2 API function looks a little different because it must return two linked channels.
