I tried to use fgetwln in place of the getline sub-routine:
if ((prevline = fgetwln(ifp, prevbuflen)) == NULL) {
:
}
while ((thisline = fgetwln(ifp, thisbuflen)) != NULL) {
:
}
But what is happening is that both thisline and prevline are being set
to the same pointer location. I need to change it to:
if ((thisline = fgetwln(ifp, thisbuflen)) == NULL) {
: /* check error */
}
prevline = strdup(thisline);
while ((thisline = fgetwln(ifp, thisbuflen)) != NULL) {
:
if (comp) {
:
/* place thisline into prevline */
prevline = strdup(thisline);
:
}
:
}
Is their a function to duplicate wchar strings?
