Tool Help Library
Overview of the Tool Help Library technology.
To develop Tool Help Library, you need these headers:
For programming guidance for this technology, see:
Functions
| CreateToolhelp32Snapshot Takes a snapshot of the specified processes, as well as the heaps, modules, and threads used by these processes. |
| Heap32First Retrieves information about the first block of a heap that has been allocated by a process. |
| Heap32ListFirst Retrieves information about the first heap that has been allocated by a specified process. |
| Heap32ListNext Retrieves information about the next heap that has been allocated by a process. |
| Heap32Next Retrieves information about the next block of a heap that has been allocated by a process. |
| Module32First The Module32First function (tlhelp32.h) retrieves information about the first module associated with a process. |
| Module32FirstW The Module32FirstW (Unicode) function (tlhelp32.h) retrieves information about the first module associated with a process. |
| Module32Next The Module32Next function (tlhelp32.h) retrieves information about the next module associated with a process or thread. |
| Module32NextW The Module32NextW (Unicode) function (tlhelp32.h) retrieves information about the next module associated with a process or thread. |
| Process32First The Process32First function (tlhelp32.h) retrieves information about the first process encountered in a system snapshot. |
| Process32FirstW The Process32FirstW (Unicode) function (tlhelp32.h) retrieves information about the first process encountered in a system snapshot. |
| Process32Next The Process32Next function (tlhelp32.h) retrieves information about the next process recorded in a system snapshot. |
| Process32NextW The Process32NextW (Unicode) function (tlhelp32.h) retrieves information about the next process recorded in a system snapshot. |
| Thread32First Retrieves information about the first thread of any process encountered in a system snapshot. |
| Thread32Next Retrieves information about the next thread of any process encountered in the system memory snapshot. |
| Toolhelp32ReadProcessMemory Copies memory allocated to another process into an application-supplied buffer. |
Structures
| HEAPENTRY32 Describes one entry (block) of a heap that is being examined. |
| HEAPLIST32 Describes an entry from a list that enumerates the heaps used by a specified process. |
| MODULEENTRY32 The MODULEENTRY32 (tlhelp32.h) structure describes an entry from a list of the modules belonging to the specified process. |
| MODULEENTRY32W The MODULEENTRY32W (Unicode) structure (tlhelp32.h) describes an entry from a list of the modules belonging to the specified process. |
| PROCESSENTRY32 The PROCESSENTRY32 (tlhelp32.h) structure describes an entry from a list of the processes residing in the system address space when a snapshot was taken. |
| PROCESSENTRY32W The PROCESSENTRY32W (Unicode) structure (tlhelp32.h) describes an entry from a list of the processes residing in the system address space when a snapshot was taken. |
| THREADENTRY32 Describes an entry from a list of the threads executing in the system when a snapshot was taken. |
