mcDBgetStream — Read from stream
#include <memcom.h>
int mcDBgetStream(int handle, char* type, mcOff address, mcSize size,
void* buffer);mcDBgetStream reads a contiguous array
data from a database in a user buffer. Data are copied from the
database starting at a given byte address. If the start address plus
the number of bytes specified exceed the current file size, the
exceeding bytes of the array are set to 0. Upon successful
completion of the operation, the status value 0 is returned. A
negative value is returned, if an error has been detected. A
positive value is returned, if a warning has been issued.
handleDatabase handle (input).
typeDataset type (input). Must be one of
K (char), I (mcInt32),
J (mcInt64), E
(mcFloat32), F (mcFloat64).
addressByte address on database where the array starts (input). The byte address must be greater or equal to 0.
sizeNumber of elements to be read from the file to
buffer (input).
bufferBuffer containing data to be transferred (input). The
data must correspond to the dataset type specified by the
type parameter.
