void myfree_movable_fullinfo	(	void *	p,
		const char *	func,
		const char *	file,
		int	line,
		int	movable_flag
	)

Deallocate a movable memory block.

For this operation to be successful all the blocks allocated after the block that has to be freed must be of movable type.

Parameters

p	pointer to the memory block to be deallocated
func	name of function that has called the deallocation routine (usually given by the FUNCTION macro)
file	file where the function that has called the deallocation routine resides (usually given by the FILE macro)
line	line number of file where the deallocation routine was called (usually given by the LINE macro)

◆ mymalloc_init()

void mymalloc_init	(	int	maxmemsize,
		enum restart_options	restartflag
	)

Initialize memory manager.

This function initializes the memory manager. In particular, it sets the global variables of the module to their initial value and allocates the memory for the stack.

Definition at line 58 of file mymalloc.cc.

◆ mymalloc_movable_fullinfo()

void * mymalloc_movable_fullinfo	(	void *	ptr,
		const char *	varname,
		size_t	n,
		const char *	func,
		const char *	file,
		int	line,
		int	movable_flag,
		int	clear_flag,
		char *	callorigin
	)

Allocate a movable memory block and store the relative information.

Parameters

ptr	pointer to the initial memory address of the block
varname	name of the variable to be stored in the allocated block
n	size of the memory block in bytes
func	name of function that has called the allocation routine (usually given by the FUNCTION macro)
file	file where the function that has called the allocation routine resides (usually given by the FILE macro)
line	line number of file where the allocation routine was called (usually given by the LINE macro)

Returns: a pointer to the beginning of the allocated memory block

void * myrealloc_movable_fullinfo	(	void *	p,
		size_t	n,
		const char *	func,
		const char *	file,
		int	line,
		int	movable_flag
	)

Reallocate an existing movable memory block.

For this operation to be successful all the blocks allocated after the block that has to be reallocated must be of movable type.

Parameters

p	pointer to the existing memory block to be reallocated
n	the new size of the memory block in bytes
func	name of function that has called the reallocation routine (usually given by the FUNCTION macro)
file	file where the function that has called the reallocation routine resides (usually given by the FILE macro)
line	line number of file where the reallocation routine was called (usually given by the LINE macro)

Returns: a pointer to the beginning of the newly allocated memory block

Definition at line 591 of file mymalloc.cc.
