I can tell from the code that you're coming from Go. But the only thing
I found strange on a cursory glance was your error handling method of
returning a pointer that is NULL on success. I know this corresponds to
"return 0 on success", but, well I was thrown off by the "return NULL"
statements in functions indicating success. The usual pattern is to
return the error code, and pass in a pointer to the error struct that is
only filled if the return code is != 0.

This is very much a matter of taste, though, and if you prefer your
current style just keep it :)
