> The first line in this method sets the size based on the string length, which is of size_t type. On a 64-bit platform, the cast from a 64 bit unsigned integer to a 32 bit unsigned integer can result in incomplete data being written. 
> With my compiler flags (-Werror and -Wconversion), I can't compile my code that includes the client library headers.
