SHMIDCAT(1) Shared Memory Trampoline SHMIDCAT(1) NAME
shmidcat - Copies stdin/file to a shared memory block for gtkwave(1) SYNTAX
shmidcat [VCDFILE] DESCRIPTION
Copies either the file specified at the command line or stdin (if no file specified) line by line to a shared memory block. stdout will contain a shared memory ID which should be passed on to gtkwave(1). EXAMPLES
To run this program the standard way type: cat whatever.vcd | shmidcat The shared memory ID is emitted to stdout. shmidcat whatever.vcd | gtkwave -v -I whatever.sav GTKWave directly grabs the ID from stdin. LIMITATIONS
This program is mainly for illustrative and testing purposes only. Its primary use is for people who wish to write interactive VCD dumpers for gtkwave(1) as its source code may be examined, particularly the emit_string() function. It can also be used to test if an existing VCD file will load properly in interactive mode. Note that it can also be used to redirect VCD files which are written into a pipe to gtk- wave(1) in a non-blocking fashion. AUTHORS
