OCI Raw Functions

Table 19-14 describes the OCI raw functions that are described in this section.

Table 19-14 Raw Functions

Function Purpose

"OCIRawAllocSize()"

Get allocated size of raw memory in bytes

"OCIRawAssignBytes()"

Assign raw bytes to raw

"OCIRawAssignRaw()"

Assign raw to raw

"OCIRawPtr()"

Get raw data pointer

"OCIRawResize()"

Resize memory of variable-length raw

"OCIRawSize()"

Get raw size


OCIRawAllocSize()

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.

err (IN/OUT)

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 (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.

OCIRawAssignBytes()

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.

err (IN/OUT)

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().

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.

Related Functions

OCIRawAssignRaw()

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

env (IN/OUT)

The OCI environment handle initialized in object mode.

err (IN/OUT)

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().

rhs (IN)

Right-hand side (rhs) (source) of the assignment; OCIRaw data.

lhs (IN/OUT)

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

OCIErrorGet(), OCIRawAssignBytes()

OCIRawPtr()

Purpose

Gets the pointer to raw data.

Syntax

ub1 *OCIRawPtr ( OCIEnv             *env,
                 const OCIRaw       *raw );

Parameters

env (IN/OUT)

The OCI environment handle initialized in object mode.

raw (IN)

Pointer to the data of a given raw.

Comments

None.

Related Functions

OCIErrorGet(), OCIRawAssignRaw()

OCIRawResize()

Purpose

Resizes the memory of a given variable-length raw.

Syntax

sword OCIRawResize ( OCIEnv          *env, 
                     OCIError        *err,
                     ub2             new_size, 
                     OCIRaw          **raw );

Parameters

env (IN/OUT)

The OCI environment handle initialized in object mode.

err (IN/OUT)

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 (IN)

New size of the raw data in bytes.

raw (IN)

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.

OCIRawSize()

Purpose

Returns the size of a given raw in bytes.

Syntax

ub4 OCIRawSize ( OCIEnv             *env,
                 const OCIRaw       *raw );

Parameters

env (IN/OUT)

The OCI environment handle initialized in object mode.

raw (IN/OUT)

Raw whose size is returned.

Comments

None.
