Reallocate memory.

On failure is called db_memory_error().

Parameters

s	pointer to memory
n	number of newly allocated bytes

Returns

pointer to allocated memory

Make a copy of string buffer.

Allocated string buffer should be freed by db_free().

Parameters

s	source string buffer

Returns

allocated string buffer
