[dtrace-discuss] concatenate structure members into one variable

[Mehul Choube]

Hi,

I want the guid in a variable. I tried stringof(), strjoin(), copyinstr() but 
none works :(

D script:

=======

#!/usr/sbin/dtrace -s

#pragma D option quiet

typedef struct GUID {
        unsigned long Data1;
        unsigned long Data2;
        unsigned long Data3;
        unsigned char Data4[8];
}GUID_t;

pid$1::*myFunc*:entry
{
        this->ptr = arg1;
        this->sptr = (GUID_t *)copyin(this->ptr, sizeof(GUID_t));

        printf("Id: ");
        printf("%8.8X%4.4X%4.4X%2.2X%2.2X%2.2X%2.2X%2.2X%2.2X%2.2X%2.2X\\n",
                ((GUID_t *)this->sptr)->Data1, ((GUID_t *)this->sptr)->Data2, 
((GUID_t *)this->sptr)->Data3,
                ((GUID_t *)this->sptr)->Data4[0], ((GUID_t 
*)this->sptr)->Data4[1], ((GUID_t *)this->sptr)->Data4[2],
                ((GUID_t *)this->sptr)->Data4[3], ((GUID_t 
*)this->sptr)->Data4[4], ((GUID_t *)this->sptr)->Data4[5],
                ((GUID_t *)this->sptr)->Data4[6], ((GUID_t 
*)this->sptr)->Data4[7]);
}

=======

The output is:
Id: 11E109F8702B323E9CAF5000568000D000000000

Any help is greatly appreciated.



Thanks,
Mehul
