Accessing "Target Name" Bootline Parameter

[Fred]

I'm sure it's something simple, but for the life of me I can't find it
in the Wind River documentation.

I'm running vxWorks 6.6 on a PPC target. I want to access the "Target
Name" (tn=XXX) parameter supplied to the kernel on the vxWorks
bootline. Is there an API that I can call to retrieve this
information? If it matters, the code making this API call would be
inside an RTP.

How do I do it?

bootLib's functions bootStringToStruct() is what you need.

#include "bootLib.h

#define BOOT_LINE_ADRS ( 0x4200 )

BOOT_PARAMS bootParams;

bootStringToStruct ( (char *)BOOT_LINE_ADRS, &bootParams );
sprintf ( stdout, "target name = \"%s\"\n", bootParams.targetName );

Thank you - I knew it would be simple!

<grin>

Just a quick followup: this function did the trick, but it's only
available from kernel code, not from an RTP. The workaround is an easy
one: I retrieved the target name prior to launching the RTP, and
passed the target name in the RTP's argument vector.
