Function Documentation

void * mem_get

(

size_t

buf_size

)

Allocate the memory block.

This function allocates the memory block of buf_size bytes. If the memory block size is less than or equal to 4 Kbytes, then global pool manager will be used, otherwise new operator will be used.

To release allocated memory block you should call mem_put() function and provide the same memory block size!

In debug version the whole memory block is filled by 0xAA value.

Parameters:

[in]

buf_size

The memory block size in bytes.

Returns:

The allocated memory block.

See also:

mem_put()

mem_get_sized()

void mem_put	(	void *	buf,
		size_t	buf_size
	)

Release the memory block.

This function releases the memory block buf of buf_size bytes. If the memory block size is less than or equal to 4 Kbytes, then global pool manager will be used, otherwise delete operator will be used.

The memory block size buf_size should be the same as when calling mem_get()!

In debug version the whole memory block is filled by 0xAA value.

Parameters:

[in]	buf	The memory block.
[in]	buf_size	The memory block size in bytes.

mem_get()

void * mem_get_sized

(

size_t

buf_size

)

Allocate the memory block.

This function allocates the memory block of buf_size bytes. If the memory block size is less than or equal to 4 Kbytes, then global pool manager will be used, otherwise new operator will be used.

To release allocated memory block you should call mem_put_sized() function!

In debug version the whole memory block is filled by 0xAA value.

Parameters:

[in]

buf_size

The memory block size in bytes.

Returns:

The allocated memory block.

See also:

mem_put_sized()

mem_get()

void mem_put_sized

(

void *

buf

)

Release the memory block.

This function releases the memory block buf. If the memory block size is less than or equal to 4 Kbytes, then global pool manager will be used, otherwise delete operator will be used.

In debug version the whole memory block is filled by 0xAA value.

Parameters:

[in]

buf

The memory block.

mem_get_sized()

bool omni::pool::operator==	(	const Allocator< T > &	,
		const Allocator< U > &
	)			[inline]

Are two allocators equal?

The two allocators are always equal.

Returns:

true.

bool omni::pool::operator!=	(	const Allocator< T > &	,
		const Allocator< U > &
	)			[inline]

Are two allocators non-equal?

The two allocators are always equal.

Returns:

false.
