Is there any optimised way to do this?
Thanks,

Any compelling reason to go for a dynamic solution??
A static solution may not be optimized but a dynamic solution would be expensive in terms of mp units.

Hello Guys
I have a small confusion in the dynamic memory allocation concept.
If we declare a pointer say a char pointer, we need to allocate adequate memory space.
char* str = (char*)malloc(20*sizeof(char));
str = "This is a string";
But this will also work.
char* str = "This... (2 Replies)

NAME
sdt - DTrace statically defined tracing provider
DESCRIPTION
The sdt driver is a DTrace dynamic tracing provider that performs dynamic instrumentation at statically-defined locations in the Solaris
kernel.
The sdt provider allows kernel developers to explicitly create probes at formally designated locations in the operating system kernel and
loadable modules, allowing the implementor to consciously choose the points in their code that are desired probe points, and to convey some
semantic knowledge about that point with the choice of probe name and a relevant set of arguments.
The sdt driver is not a public interface and you access instrumentation offered by this provider through DTrace. Refer to the Solaris
Dynamic Tracing Guide for a description of the public documented interfaces available for the DTrace facility and the probes offered by the
sdt provider.
