Auto Assembler alloc(SymbolName, Size, AllocateNearThisAddress OPTIONAL)
Allocates a certain amount of memory and defines the symbol name in the script. If 'AllocateNearThisAddress' is specified CE will try to allocate the memory near that address. This is useful for 64-bit targets where the jump distance could be bigger than 2GB otherwise.
Note: Use dealloc to free the memory when done.
Note2: There are 2 other alloc variants. allocnx and allocxo. allocnx will allocate memory as non-executable. allocxo will allocate memory as execute only
Command Parameters
| Parameter | Type | Description |
|---|---|---|
| SymbolName | string | The symbol name to use for allocated memory |
| Size | integer | The byte size of the block of memory to allocate |
| AllocateNearThisAddress | string | The address to allocate near if given |
Examples
alloc(SomeSymbol, 0x4)
alloc(SomeSymbol, 0x1000)
alloc(SomeSymbol, $1000)
alloc(SomeSymbol, 0x4, Tutorial-x86_64.exe+164C2)
- From the SunBeam: CE actually fetches the module and allocates close to the end of the module. Additionally specifying +164C2 does not add to it in any way :D Jus' sayin' Tutorial-x86_64.exe is enough.post
