SYNOPSIS
#include <vrb.h>
size_t vrb_space_len(vrb_p vrb);
DESCRIPTION
vrb_space_len returns the total length of space available in the given virtual ring buffer. This is the maximum space the caller may store
into the buffer from the pointer returned by vrb_space_ptr(3).
ARGUMENTS
vrb_p vrb
specifies the virtual ring buffer to obtain the length of available space in. If a NULL or invalid pointer is given, results are unpre-
