Equivalent for dcraw -c?

This is document for dcraw -c:

Raw photo decoder "dcraw" v9.28
by Dave Coffin, dcoffin a cybercom o net
 
Usage:  dcraw [OPTION]... [FILE]...
 
-v        Print verbose messages
-c        Write image data to standard output

But -c is used for other purposes in libraw:

dcraw_emu: almost complete dcraw emulator
Usage:  dcraw_emu [OPTION]... [FILE]...
-c float-num       Set adjust maximum threshold (default 0.75)

How should I do the same thing in libraw? I need to use this for Imagemagick delegation. Thanks!

Since 201812 snapshot:

Since 201812 snapshot:

* dcraw_emu: it is now possible to create output filename in a more flexible manner, via -Z switch:
-Z - will output to stdout
-Z ext will output into inputfilename.ext
-Z .ext will output into inputfilename.inputext.ext

I'm running the latest binary

I'm running the latest binary build 0.19.2 but the -Z appears not to be implimented.

Is the 201812 snapshot newer/different branh? If so, where can I get the Win64 binaries?

Thanks in advance!

We do not full release cycle

We do not do full release cycle for snapshots (only for releases), this is source-code only

Public snapshot source code could be obtained from GitHub: https://github.com/LibRaw/LibRaw/ (master branch)
To compile with MS Visual Studio use nmake -f Makefile.msvc
