Definition in file MemoryAllocationLib.c.
Allocates one or more 4KB pages of type EfiBootServicesData at a specified alignment.
Allocates the number of 4KB pages specified by Pages of type EfiBootServicesData with an alignment specified by Alignment. The allocated buffer is returned. If Pages is 0, then NULL is returned. If there is not enough memory at the specified alignment remaining to satisfy the request, then NULL is returned. If Alignment is not a power of two and Alignment is not zero, then ASSERT().
Pages | The number of 4 KB pages to allocate. |
Alignment | The requested alignment of the allocation. Must be a power of two. If Alignment is zero, then byte alignment is used. |

Allocates one or more 4KB pages of type EfiBootServicesData.
Allocates the number of 4KB pages of MemoryType and returns a pointer to the allocated buffer. The buffer returned is aligned on a 4KB boundary. If Pages is 0, then NULL is returned. If there is not enough memory remaining to satisfy the request, then NULL is returned.
Pages | The number of 4 KB pages to allocate. |

Allocates a buffer of type EfiBootServicesData.
Allocates the number bytes specified by AllocationSize of type EfiBootServicesData and returns a pointer to the allocated buffer. If AllocationSize is 0, then a valid buffer of 0 size is returned. If there is not enough memory remaining to satisfy the request, then NULL is returned.
AllocationSize | The number of bytes to allocate. |
Definition at line 168 of file MemoryAllocationLib.c.
Allocates and zeros a buffer of type EfiBootServicesData.
Allocates the number bytes specified by AllocationSize of type EfiBootServicesData, clears the buffer with zeros, and returns a pointer to the allocated buffer. If AllocationSize is 0, then a valid buffer of 0 size is returned. If there is not enough memory remaining to satisfy the request, then NULL is returned.
AllocationSize | The number of bytes to allocate and zero. |

Frees one or more 4KB pages that were previously allocated with one of the page allocation functions in the Memory Allocation Library.
Frees the number of 4KB pages specified by Pages from the buffer specified by Buffer. Buffer must have been allocated on a previous call to the page allocation services of the Memory Allocation Library. If it is not possible to free allocated pages, then this function will perform no actions.
If Buffer was not allocated with a page allocation function in the Memory Allocation Library, then ASSERT(). If Pages is zero, then ASSERT().
Buffer | Pointer to the buffer of pages to free. |
Pages | The number of 4 KB pages to free. |

Frees a buffer that was previously allocated with one of the pool allocation functions in the Memory Allocation Library.
Frees the buffer specified by Buffer. Buffer must have been allocated on a previous call to the pool allocation services of the Memory Allocation Library. If it is not possible to free pool resources, then this function will perform no actions.
If Buffer was not allocated with a pool allocation function in the Memory Allocation Library, then ASSERT().
Buffer | Pointer to the buffer to free. |
