Debugger on Solaris

[Waldek Hebisch]

Patric sed a trace:

open("/proc/11664", O_RDWR)                     = 3
ioctl(3, PIOCSTATUS, 0x081811E0)                = 0
ioctl(3, PIOCOPENLWP, 0x080476C8)               = 4
ioctl(4, PIOCSET, 0x080476C4)                   = 0
close(3)                                        = 0
ioctl(4, PIOCGTRACE, 0x0818163C)                = 0
ioctl(4, PIOCGHOLD, 0x08181614)                 = 0
ioctl(4, PIOCGFAULT, 0x08181628)                = 0
....

That looks pretty clear. However manual in Solaris 2.6 says 
that one should open /proc/pid/ctl for writing and 
specifyes messages to perform debug actions. Manual also 
suggests that ptrace is a library function working with 
proc filesystem so the only question is wether to use 
ioctl on /proc/pid or write to /proc/pid/ctl.
