template<typename T>

static FORCEINLINE int MemCmpT | ( | const T * | ptr1,
|  | const T * | ptr2,
|  | size_t | num = `1` |
| ) |  |  | `[inline, static]`

Type-safe version of memcmp().

Parameters:

  | ptr1 | Pointer to the first buffer
  | ptr2 | Pointer to the second buffer
  | num | Number of items to compare. (!not number of bytes!)

Returns:
  an int value indicating the relationship between the content of the two buffers

static FORCEINLINE void MemCpyT | ( | T * | destination,
|  | const T * | source,

| ) |  |  | `[inline, static]`

Type-safe version of memcpy().

Parameters:

  | destination | Pointer to the destination buffer
  | source | Pointer to the source buffer
  | num | number of items to be copied. (!not number of bytes!)

|  | size_t | num = `1` |
| ) |  |  | `[inline, static]`

Type-safe version of memmove().

Parameters:

  | destination | Pointer to the destination buffer

template<typename T>

static FORCEINLINE void MemReverseT | ( | T * | ptr,
|  | size_t | num |
| ) |  |  | `[inline, static]`

Type safe memory reverse operation (overloaded).

Parameters:

  | ptr | Pointer to the block of memory.
  | num | The number of items we want to reverse.

Definition at line 97 of file mem_func.hpp.

template<typename T>

static FORCEINLINE void MemReverseT | ( | T * | ptr1,
|  | T * | ptr2 |
| ) |  |  | `[inline, static]`

Type safe memory reverse operation.

Reverse a block of memory in steps given by the type of the pointers.

Parameters:

  | ptr1 | Start-pointer to the block of memory.
  | ptr2 | End-pointer to the block of memory.

| ) |  |  | `[inline, static]`

Type-safe version of memset().

Parameters:

  | ptr | Pointer to the destination buffer
  | value | Value to be set
  | num | number of items to be set (!not number of bytes!)
