OCIStringResize()

Purpose

Resizes the memory of a given string.

Syntax

sword OCIStringResize ( OCIEnv          *env,
                        OCIError        *err,
                        ub4             new_size,
                        OCIString       **str );

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 memory size of the string in bytes. new_size must include space for the NULL character as the string terminator.

str (IN/OUT)

Allocated memory for the string which is freed from the OCI object cache.

Comments

This function resizes the memory of the given variable-length string in the object cache. Contents of the string are not preserved. This function may allocate the string in a new memory region, in which case the original memory occupied by the given string is freed. If str is null, this function allocates memory for the string. If new_size is 0, this function frees the memory occupied by str and a null pointer value is returned.
