A 'pseudo' Hal component is created in order to make:
threadname.time pin (output only for halscope, hal-histogram, etc)
threadname.tmax param (rw so it can be reset)
The pseudo component name is identified by the prefix:
HAL_PSEUDO_COMP_PREFIX = "__"
Example:
$ halcmd show comp __
Loaded HAL Components:
ID Type Name PID State
17 RT __servo-thread ready
16 RT __base-thread ready
$ halcmd show pin \*thread\*
Component Pins:
Owner Type Dir Value Name
22 s32 OUT 26040 servo-thread.time ==> hhs-0
$ halcmd show param \*thread\*
Parameters:
Owner Type Dir Value Name
22 s32 RW 147280 servo-thread.tmax
Note:
removed two #if 0 sections for comments about adding this functionality
tested on
ubuntu lucid rtai
debian wheezy uspace
Alternate to using a coded prefix for a 'pseudo' component:
Consider changing the hal_comp_t struct type field from an
int to an enum and modifying hal_init() to accept an arg
for special comp types. As hal_init() is used many places,
this method is probably too pervasive for upcoming 2.7 release.

Checks that 'halcmd save' produces the expected output, including loadable module parameters, parameter settings, linked pins, and thread functions.
