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.
