Further routines
The concatenation of two vectors:
- NAME: append_vector
- SYNOPSIS: INT append_vector(OP a,b,c)
- DESCRIPTION: a,b should be VECTORobjects, c the empty object.
The routine bulids an new VECTORobject c, where the
first part is a copy of a and the second part a copy of
b.
- RETURN: OK, or ERROR
- BUG: there is no check on types, because this is a special
routine, normally you should use append instead.
Comparing two vectors with respect to lexicographic ordering:
- NAME: comp_vector
- SYNOPSIS: INT comp_vector(OP a,b)
- DESCRIPTION: a,b should be VECTORobjects, the routine does
lexicographic comparision.
- RETURN: 0 = equal, <0 if a <b, >0 if a>b
- BUG: there is no check on types, because this is a special
routine, normally you should use comp instead.
Copying can be done as follows:
- NAME: copy_vector
- SYNOPSIS: INT copy_vector(OP a,b)
- DESCRIPTION: a should be a VECTORobject, b the empty object.
b becomes a copy of a. a and b must be different. This
routine is called by other copy routines,
which copy objects with VECTOR type components.
- RETURN: OK, or ERROR
- BUG: there is no check on types, and there is no check
whether a and b are different. Because this is a special
routine, normaly you should use copy instead.
