# Allocator
This part of the library implements custom memory management functions for both windows and linux devices.
## Featurs
* Setting memory
* Copying memory
* Moving memory
* Comparing memory
## Usage
### Error handling
When using `hallocy_set_memory`, `hallocy_copy_memory` or `hallocy_move_memory` they will return a HallocyError. This error should be handled correctly to avoid any futher problems.
## Functions
### Set memory
Sets specified block of memory to specified value.
```c
HallocyError hallocy_set_memory(void *destination, int value, const size_t size);
```
- `destination`: The memory to set the value of.
- `value`: The value to set the memory in destination to.
- `size`: The size of the memory in bytes to set the value of.
### Copy memory
Copies memory from one pointer to another pointer.
```c
HallocyError hallocy_copy_memory(void *destination, void *source, const size_t size);
```
- `destination`: The memory to copy the values to.
- `source`: The memory to copy the values from.
- `size`: The size of the memory in bytes to copy the value to.
### Move memory
Copies memory from one pointer to another pointer. Unlike the `hallocy_copy_memory` function this function will handle overlapping memory right.
```c
HallocyError hallocy_move_memory(void *destination, void *source, const size_t size);
```
- `destination`: The memory to copy the values to.
- `source`: The memory to copy the values from.
- `size`: The size of the memory in bytes to copy the value to.
### Compare memory
```c
bool hallocy_compare_memory(void *left_side, void *right_side, const size_t size);
```
- `left_side`: The memory to compare with the right side.
- `right_side`: The memory to compare with the left side.
- `size`: The size of the memory in bytes to compare the value to.
## Example usage
```c
#include <Hallocy/Core/Allocator.h>
#include <Hallocy/Core/Memory.h>
#include <Hallocy/Utils/Error.h>
int main() {
char *allocated_memory = hallocy_malloc(128 * sizeof(char));
if (allocated_memory == NULL) {
return -1;
}
HallocyError error = hallocy_memory_set(allocated_memory, 'T', 127);
if (error != HALLOCY_ERROR_NONE) {
return -1; // Check type of error here instead of returning -1 imidiatly.
}
error = hallocy_free(allocated memory);
if (error != HALLOCY_ERROR_NONE) {
return -1; // Check type of error here instead of returning -1 imidiatly.
}
return 0;
}
```
