cuda.bindings.cufile.writev( intptr_t fh, IOVec iov, off_t file_offset, unsigned int flags=0, )#

Write data to a registered file handle from a gather list of device or host buffers.

Parameters:

fh (intptr_t) – CUfileHandle_t opaque file handle.
iov (IOVec) – scatter/gather descriptor array; each element specifies a base pointer (device or host) and a byte length.
file_offset (off_t) – file offset from the beginning of the file.
flags (unsigned int) – reserved; must be 0.

Returns:

number of bytes written on success.

Return type:

ssize_t
