typedef off_t hoff_t

Platform-independent offset type.

Definition at line 107 of file hipfile.h.

Synchronously read data from a file into a GPU buffer.

Parameters

[in]	fh	\hipfile_handle_param
[in]	buffer_base	\buffer_base_param
[in]	size	Number of bytes that should be read
[in]	file_offset	Offset into the file that should be read from
[in]	buffer_offset	Offset of the GPU buffer that that the data should be written to

\max_io_size_note

Returns: if >= 0: Number of bytes read; if -1: System error (check errno for the specific error); else: Negative value of the related hipFileOpError_t

Synchronously write data from a GPU buffer to a file.

Parameters

[in]	file_offset	Offset into the file that should be written to
[in]	buffer_offset	Offset of the GPU buffer that the data should be read from

\max_io_size_note

Returns: if >= 0: Number of bytes written; if -1: System error (check errno for the specific error); else: Negative value of the related hipFileOpError_t
