Detailed Description

varbuf_init must be called exactly once before the use of each varbuf (including before any call to varbuf_destroy), or the variable must be initialized with VARBUF_INIT.

However, varbufs allocated ‘static’ are properly initialized anyway and do not need varbuf_init; multiple consecutive calls to varbuf_init before any use are allowed.

varbuf_destroy must be called after a varbuf is finished with, if anything other than varbuf_init has been done. After this you are allowed but not required to call varbuf_init again if you want to start using the varbuf again.

Callers using C++ need not worry about any of this.
