Function Documentation

cbmimage_alloc_set_functions()

int cbmimage_alloc_set_functions	(	cbmimage_alloc_xalloc_function_type	xalloc_function,
		cbmimage_alloc_xfree_function_type	xfree_function,
		cbmimage_alloc_xalloc_and_copy_function_type	xalloc_and_copy_function )

set the callback for output from the library

Parameters

[in]

xalloc_function

pointer to the function that is called whenever the library wants to xalloc() something

If this is set to NULL, then a library internal xalloc() is used

Parameters

[in]

xfree_function

pointer to the function that is called whenever the library wants to xfree() something

If this is set to NULL, then a library internal xfree() is used

Parameters

[in]

xalloc_and_copy_function

pointer to the function that is called whenever the library wants to xalloc_and_copy() something

If this is set to NULL, then a library internal xalloc_and_copy() is used

Remarks

• xalloc_function and xfree_function must correspond to each other. Because of this, do not set one of these functions, but not the other!
• If xalloc_and_copy_function is set, it must correspond to xalloc_function, too. However, if it is not defined (= NULL), then an internal implementation is used that used xalloc_function; thus, in this case, the usage is safe
