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 will be freed. If the input raw is null (raw == NULL), then this function will allocate 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.
