- When the run-time library calls your hook, the *nAllocType* argument indicates what allocation operation is about to be made (**_HOOK_ALLOC**, **_HOOK_REALLOC**, or **_HOOK_FREE**). In a free or in a reallocation, `pvData` has a pointer to the user article of the block about to be freed. However for an allocation, this pointer is null, because the allocation hasn't occurred. The remaining arguments contain the size of the allocation in question, its block type, the sequential request number associated with it, and a pointer to the file name. If available, the arugments also include the line number in which the allocation was made. After the hook function performs whatever analysis and other tasks its author wants, it must return either **TRUE**, indicating that the allocation operation can continue, or **FALSE**, indicating that the operation should fail. A simple hook of this type might check the amount of memory allocated so far, and return **FALSE** if that amount exceeded a small limit. The application would then experience the kind of allocation errors that would normally occur only when available memory was very low. More complex hooks might keep track of allocation patterns, analyze memory use, or report when specific situations occur.
