NAME

memory - Memory Allocation

SYNOPSIS

void * AcquireMagickMemory( const size_t size );

void * CopyMagickMemory( void *destination, const void *source, const size_t size );

void * RelinquishMagickMemory( void *memory );

void * ResetMagickMemory( void *memory, int byte, const size_t size );

void * ResizeMagickMemory( void *memory, const size_t size );

FUNCTION DESCRIPTIONS

AcquireMagickMemory

AcquireMagickMemory() returns a pointer to a block of memory at least size bytes suitably aligned for any use.

The format of the AcquireMagickMemory method is:

void *AcquireMagickMemory ( const size_t size );

A description of each parameter follows:

size:

The size of the memory in bytes to allocate.

CopyMagickMemory

CopyMagickMemory() copies size bytes from memory area source to the destination. Copying between objects that overlap will take place correctly. It returns destination.

The format of the CopyMagickMemory method is:

void *CopyMagickMemory ( void *destination, const void *source, const size_t size );

A description of each parameter follows:

destination:

The destination.

source:

The source.

size:

The size of the memory in bytes to allocate.

RelinquishMagickMemory

RelinquishMagickMemory() zeros memory that has been allocated, frees it for reuse.

The format of the RelinquishMagickMemory method is:

void *RelinquishMagickMemory ( void *memory );

A description of each parameter follows:

memory:

A pointer to a block of memory to free for reuse.

ResetMagickMemory

ResetMagickMemory() fills the first size bytes of the memory area pointed to by memory with the constant byte c.

The format of the ResetMagickMemory method is:

void *ResetMagickMemory ( void *memory, int byte, const size_t size );

A description of each parameter follows:

memory:

A pointer to a memory allocation.

byte:

Set the memory to this value.

size:

Size of the memory to reset.

ResizeMagickMemory

ResizeMagickMemory() changes the size of the memory and returns a pointer to the ( possibly moved ) block. The contents will be unchanged up to the lesser of the new and old sizes.

The format of the ResizeMagickMemory method is:

void *ResizeMagickMemory ( void *memory, const size_t size );

A description of each parameter follows:

memory:

A pointer to a memory allocation.

size:

The new size of the allocated memory.
