Non-interfering status inquiry for user threads
First Claim
1. A method of obtaining status information from user threads of a target process, the method comprising:
- performing a system call from a querying process;
creating a kernel debug thread in a kernel entity of the target process;
creating a user status thread in a user entity of the target process; and
collecting status information by the user status thread from other user threads of the target process.

Abstract
One embodiment disclosed relates to a method of obtaining status information from user threads of a target process. A system call is performed from a querying process. The system call creates a kernel debug thread in a kernel entity of the target process. The kernel debug thread further creates a user status thread in a user entity of the target process. The method may be used to obtain the status information without stopping the target process. Another embodiment disclosed relates to an operating system with capability to obtain status information from user threads of a target process. The operating system includes at least the following first and second system calls. The first system call is configured to create a kernel debug thread in a kernel entity of the target process. The second system call is configured to awake the kernel debug thread and pass information to the kernel debug thread.

12. A computer apparatus having an operating system with capability to obtain status information from user threads of a target process so as to debug the target process without requiring stopping the target process, the computer apparatus comprising:
-
a processor configured to execute program instructions; memory configured to store program instructions and data; and processor-readable instructions for a first system call configured to create a kernel debug thread in a kernel entity of the target process; and processor-readable instructions for a second system call configured to awake the kernel debug thread and pass information to the kernel debug thread. - View Dependent Claims (13, 14)
