Enumeration Type Documentation

H5FD_file_image_op_t

enum H5FD_file_image_op_t

Define enum for the source of file image callbacks

Enumerator
H5FD_FILE_IMAGE_OP_NO_OP
H5FD_FILE_IMAGE_OP_PROPERTY_LIST_SET	Passed to the image_malloc and image_memcpy callbacks when a file image buffer is to be copied while being set in a file access property list (FAPL)
H5FD_FILE_IMAGE_OP_PROPERTY_LIST_COPY	Passed to the image_malloc and image_memcpy callbacks when a file image buffer is to be copied when a FAPL is copied
H5FD_FILE_IMAGE_OP_PROPERTY_LIST_GET	Passed to the image_malloc and image_memcpy callbacks when a file image buffer is to be copied while being retrieved from a FAPL
H5FD_FILE_IMAGE_OP_PROPERTY_LIST_CLOSE	Passed to the image_free callback when a file image buffer is to be released during a FAPL close operation
H5FD_FILE_IMAGE_OP_FILE_OPEN	Passed to the image_malloc and image_memcpy callbackswhen a file image buffer is to be copied during a file open operation While the file image being opened will typically be copied from a FAPL, this need not always be the case. For example, the core file driver, also known as the memory file driver, takes its initial image from a file.
H5FD_FILE_IMAGE_OP_FILE_RESIZE	Passed to the image_realloc callback when a file driver needs to resize an image buffer
H5FD_FILE_IMAGE_OP_FILE_CLOSE	Passed to the image_free callback when an image buffer is to be released during a file close operation
