28.5.1 OCIRawAllocSize()
Gets the allocated size of raw memory in bytes.
Purpose
Gets the allocated size of raw memory in bytes.
Syntax
sword OCIRawAllocSize ( OCIEnv *env, OCIError *err, const OCIRaw *raw, ub4 *allocsize );
Parameters
- env (IN/OUT)
-
The OCI environment handle initialized in object mode. See the descriptions of
OCIEnvCreate()
,OCIEnvNlsCreate()
, andOCIInitialize()
(deprecated) for more information. - err (IN/OUT)
-
The OCI error handle. If there is an error, it is recorded in
err
, and this function returnsOCI_ERROR
. Obtain diagnostic information by callingOCIErrorGet()
. - raw (IN)
-
Raw data whose allocated size in bytes is returned. This must be a non-
NULL
pointer. - allocsize (OUT)
-
The allocated size of raw memory in bytes that is returned.
Comments
The allocated size is greater than or equal to the actual raw size.
28.5.2 OCIRawAssignBytes()
Assigns raw bytes of type ub1*
to Oracle OCIRaw*
data type.
Purpose
Assigns raw bytes of type ub1*
to Oracle OCIRaw*
data type.
Syntax
sword OCIRawAssignBytes ( OCIEnv *env, OCIError *err, const ub1 *rhs, ub4 rhs_len, OCIRaw **lhs );
Parameters
- env (IN/OUT)
-
The OCI environment handle initialized in object mode. See the descriptions of
OCIEnvCreate()
,OCIEnvNlsCreate()
, andOCIInitialize()
(deprecated) for more information. - err (IN/OUT)
-
The OCI error handle. If there is an error, it is recorded in
err
, and this function returnsOCI_ERROR
. Obtain diagnostic information by callingOCIErrorGet()
. - rhs (IN)
-
Right-hand side (source) of the assignment, of data type
ub1
. - rhs_len (IN)
-
Length of the
rhs
raw bytes. - lhs (IN/OUT)
-
Left-hand side (target) of the assignment
OCIRaw
data.
Comments
Assigns rhs
raw bytes to lhs
raw data type. The lhs
raw may be resized depending upon the size of the rhs
. The raw bytes assigned are of type ub1
.

Parameters
- env (IN/OUT)
-
The OCI environment handle initialized in object mode. See the descriptions of
OCIEnvCreate()
,OCIEnvNlsCreate()
, andOCIInitialize()
(deprecated) for more information. - err (IN/OUT)
-
The OCI error handle. If there is an error, it is recorded in
err
, and this function returnsOCI_ERROR
. Obtain diagnostic information by callingOCIErrorGet()
. - new_size (IN)
-
New size of the raw data in bytes.
- raw (IN)
-
Variable-length
raw
pointer; theraw
is resized tonew_size
.
Comments
This function resizes the memory of the given variable-length raw in the object cache. The previous contents of the raw are not preserved. This function may allocate the raw in a new memory region in which case the original memory occupied by the given raw is freed. If the input raw is NULL
(raw
== NULL
), then this function allocates memory for the raw data.
If the new_size
is 0, then this function frees the memory occupied by raw
, and a NULL
pointer value is returned.
