Stops sample code profiling.

Parameters

• [out] rc – return code.

N/A

SamplingRead

Purpose

Gets data containing the code execution statistics received from sample profiling.

Parameters

• [in] unsafeBuffer – pointer to the buffer used to save the data on the code execution statistics obtained from profiling.
• [in] size – size of the buffer whose pointer is defined through the unsafeBuffer parameter in bytes.
• [out] realSize – size of the saved data in bytes.
• [in] timeout – container filling timeout (in milliseconds).
• [out] rc – return code.

Gets the addresses and names of functions of other processes.

SamplingAddPidToList

Purpose

Adds a process to the set of processes in whose contexts the programs subject to sample profiling are running.

Parameters

• [in] pid – process ID (PID).
• [out] rc – return code.

N/A

SamplingClearPidList

Purpose

Clears the set of processes in whose contexts the programs subject to sample profiling are running.

Parameters

• [out] rc – return code.

N/A

LoadSegInfo

Purpose

Saves information about the loaded segment of the ELF image in the kernel.

Parameters

• [in] task – value whose binary representation consists of multiple fields, including a handle field and a handle permissions mask field. The handle identifies the process.
• [in] addr – segment address in process memory.
• [in] size – segment size (in bytes).
• [in] offset – offset of the segment in the ELF file (in bytes).
• [in] flags – flags defining the access rights to the segment.
• [in] buildId – build ID.
• [out] rc – return code.

Allows the kernel memory to be used up by creating a multitude of objects within it.

UnloadSegInfo

Purpose

Deletes information about the loaded ELF image segment that was saved in the kernel using the LoadSegInfo method.

Parameters

• [in] task – value whose binary representation consists of multiple fields, including a handle field and a handle permissions mask field. The handle identifies the process.
• [in] addr – segment address in process memory.
• [in] size – segment size (in bytes).
• [out] rc – return code.

N/A
