Table 20-14 Raw Functions
Function | Purpose |
---|---|
Get allocated size of raw memory in bytes |
|
Assign raw bytes to raw |
|
Assign raw to raw |
|
Get raw data pointer |
|
Resize memory of variable-length raw |
|
Get raw size |
Purpose
Gets the allocated size of raw memory in bytes.
Syntax
sword OCIRawAllocSize ( OCIEnv *env, OCIError *err, const OCIRaw *raw, ub4 *allocsize );
Parameters
The OCI environment handle initialized in object mode.
See Also:
"OCIEnvCreate()", "OCIEnvNlsCreate()", and "OCIInitialize()" (deprecated)
The OCI error handle. If there is an error, it is recorded in err
, and this function returns OCI_ERROR
. Obtain diagnostic information by calling OCIErrorGet().
Raw data whose allocated size in bytes is returned. This must be a non-NULL
pointer.
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.
Related Functions
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
The OCI environment handle initialized in object mode.
See Also:
"OCIEnvCreate()", "OCIEnvNlsCreate()", and "OCIInitialize()" (deprecated)
The OCI error handle. If there is an error, it is recorded in err
, and this function returns OCI_ERROR
. Obtain diagnostic information by calling OCIErrorGet().
Right-hand side (source) of the assignment, of data type ub1
.
Length of the rhs
raw bytes.
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
.
Related Functions
Purpose
Assigns one Oracle RAW
data type to another Oracle RAW
data type.
Syntax
sword OCIRawAssignRaw ( OCIEnv *env, OCIError *err, const OCIRaw *rhs, OCIRaw **lhs );
Parameters
The OCI environment handle initialized in object mode.
See Also:
"OCIEnvCreate()", "OCIEnvNlsCreate()", and "OCIInitialize()" (deprecated)
The OCI error handle. If there is an error, it is recorded in err
, and this function returns OCI_ERROR
. Obtain diagnostic information by calling OCIErrorGet().
Right-hand side (rhs
) (source) of the assignment; OCIRaw
data.
Left-hand side (lhs
) (target) of the assignment; OCIRaw
data.
Comments
Assigns rhs
OCIRaw
to lhs
OCIRaw
. The lhs
OCIRaw
may be resized depending upon the size of the rhs
.
Related Functions
Purpose
Gets the pointer to raw data.
Syntax
ub1 *OCIRawPtr ( OCIEnv *env, const OCIRaw *raw );
Parameters
The OCI environment handle initialized in object mode.
See Also:
"OCIEnvCreate()", "OCIEnvNlsCreate()", and "OCIInitialize()" (deprecated)
Pointer to the data of a given raw
.
Comments
None.
Related Functions
Purpose
Resizes the memory of a given variable-length raw
.
Syntax
sword OCIRawResize ( OCIEnv *env, OCIError *err, ub2 new_size, OCIRaw **raw );
Parameters
The OCI environment handle initialized in object mode.
See Also:
"OCIEnvCreate()", "OCIEnvNlsCreate()", and "OCIInitialize()" (deprecated)
The OCI error handle. If there is an error, it is recorded in err
, and this function returns OCI_ERROR
. Obtain diagnostic information by calling OCIErrorGet().
New size of the raw data in bytes.
Variable-length raw
pointer; the raw
is resized to new_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.
Related Functions
Purpose
Returns the size of a given raw in bytes.
Syntax
ub4 OCIRawSize ( OCIEnv *env, const OCIRaw *raw );
Parameters
The OCI environment handle initialized in object mode.
See Also:
"OCIEnvCreate()", "OCIEnvNlsCreate()", and "OCIInitialize()" (deprecated)
Raw whose size is returned.
Comments
None.
