Not quite. The base characters have a combining class of 0, while for
the combining ones that value is > 0 but not necessarily the same. For
example:
a +ˉ + ˳ (0 + 230 + 220)
So the code needs to capture sequences starting with class of 0 and
followed by one or more chars with class > 0:
int32_t prev; /* Last class transition */
uint8_t class = 0;
while ( /* iterate backward over string */ ) {
while (u_getCombiningClass(codept) > 0) {
/* Get 'next' codept */
}
/* Copy codepts from 'next' to 'prev' */
prev = current point of iteration;
}

OK, so I guess the code should track the combining class and copy out
chunks of codepoints with the same class, something like:
int32_t prev; /* Last class transition */
uint8_t class = 0;
while ( /* iterate backward over string */ ) {
while (u_getCombiningClass(codept) == class) {
/* Get 'next' codept */
}
/* Copy codepts from 'next' to 'prev' */
}
Is that correct ?
