"error:"

[gbettega]

Hello,
my question could be stupid, and due to a lack of knowledge.

In fuction

/----------------------------------------------------------
| Check if an object is contained in a provided list
----------------------------------------------------------/
static inline tmBool OBJ_IN_LIST(void *obj, tmList *list)
{
tmListNode *cur;
for (cur = list->first; cur != NULL; cur = cur->next)
if ( cur->value == obj )
return TRUE;

return FALSE;
error:
return -1;
}

what is

"error: "

at the end of the function?
Thanks
Giovanni

Hi Giovanni,

thats a pattern I used at the time I wrote this code that can be used to handle a fallback in case of invalid checks (which are actually not used in this function, so the error block is useless - so you can basically ignore it ...).

It depends on the file src/tmesh/include/tmesh/dbg.h which originally stems from Zed Shaws Learn C the hard way. The file contains a check() function, that automatically leads to an "error" block when check() is invalid.

Cheers
Flo
