void* mem_alloc

(

size_t

nbytes

)

allocate memory

mem_alloc uses malloc to allocate the required sized chunk of memory. If any error is returned from malloc() a fatal diagnostic is issued.

Parameters:

nbytes

The size of the memory to allocate.

Warning:

It is the responsibility of the caller to ensure that the space is freed when finished with, by a call to mem_free().

void* mem_alloc_clear

(

size_t

nbytes

)

allocate and clear memory

mem_alloc_clear uses malloc to allocate the required sized chunk of memory. If any error is returned from malloc() an fatal diagnostic is issued. The memory is zeroed befor it is returned.

Parameters:

nbytes

The size of the memory to allocate

Warning:

It is the responsibility of the caller to ensure that the space is freed when finished with, by a call to free().

void* mem_change_size	(	void *	,
		size_t
	)

char* mem_copy_string

(

const char *

arg

)

The mem_copy_string function may be used to copy a C string into dynamically allocated memory.

Parameters:

arg	The NUL terminated string to be copied.

Returns:

A copy of the string in dynamic memory. Use mem_free when you are done with it.

char* mem_copy_string	(	const char *	arg,
		size_t	len
	)

The mem_copy_string function may be used to copy a string into dynamically allocated memory.

Parameters:

arg	The string to be copied (it is *not* NUL terminated).
len	The length of the string to be copied.

Returns:

A copy of the string in dynamic memory. The copy *is* NUL terminated. Use mem_free when you are done with it.
