home pp_unbalanced_if_action
Category: Preprocessor options
Type: numeric [0 .. 2]
Default: 0
Action to perform when unbalanced #if and #else blocks are found.
0: do nothing
1: print a warning message
2: terminate the program with an error (EX_SOFTWARE)
The action will be triggered in the following cases:
- if an #ifdef block ends on a different indent level than
where it started from. Example:
#ifdef TEST
int i;
{
int j;
#endif
- an #elif/#else block ends on a different indent level than
the corresponding #ifdef block. Example:
#ifdef TEST
int i;
#else
}
int j;
#endif
