In the process of trying to deal with the vls regression failure on
32-bit *nix systems I see the need for some hackery for an old type
specifier. The hack involves creating a tmp bu_vls as a copy of the
current format string and modifying it.
I see no function to deal with changing individual bu_vls characters.
Have I just missed them or should I just access the bu_vls string
directly?
Maybe we need a function like bu_vls_readc (for reading) and
bu_vls_exchc (for substituting).
(Note there is an existing appending bu_vls_putc function.)
I envision them like this:
int
bu_vls_readc(struct bu_vls *vp, const size_t pos)
{
BU_CK_VLS(vp);
/* error to request past end char */
if (pos >= vp->vls_len)
return -1;
else
return vp->vls_str[vp->vls_offset + pos];
}
int
bu_vls_exchc(struct bu_vls *vp, const size_t pos, const int c)
{
BU_CK_VLS(vp);
/* error to request past ending char */
if (pos >= vp->vls_len)
return -1;
else {
vp->vls_str[vp->vls_offset + vp->pos] = (char)c;
/* allow the caller to check for proper handling */
return vp->vls_str[vp->vls_offset + vp->pos];
}
}
Best regards,
