Where has "strpos" gone?

Post by siggi »

According to WIKI it is contained in "string.h". But that is no more given in current z88dk
When I compile my old sendmail program at ZX81, result is:

Code: Select all

D:\PRIVAT\ZX81\DEV\LAN\sendmail>zcc +zx81 -startup=2 -create-app -vn -O3 -o smai
l.bin mini_sendmail-V2.3.c -llibsocket -llibhttp

BTW: The line nummers given in the error messages do not really help. This are the real line numbers, where the C-file calls strpos:

Code: Select all

Suche "strpos" im aktiven Dokument

D:\PRIVAT\ZX81\DEV\LAN\sendmail\mini_sendmail-V2.3.c
   186: status = strpos(username, '?');
   209: status = strpos(reply_to, '?');
   362: i = strpos(buf, '?');

I don't have information about its removal, but I understand it is not in the posix standard. The equivalent function should be strstr().
The wrong line numbers being reported is for another known bug.
Please confirm it is a valid workaround and let me know what link in the wiki is reporting the wrong information. ;)

Yes, I used it and now I can compile sendmail (which can be started and also crashes when using some (not all!) ZeddyNet functions).

classic is now using the newlib string functions which doesn't have strpos (it's not posix and is a non-posix equivalent to strstr as mentioned). Classic retained a couple of other string functions not in newlib but missed / deliberately omitted strpos.
