a warning, return 1 instead of 0 to indicate that we didn't print anything, so that top-level callers don't print a spurious newline. This is mainly to fix output formatting when stderr is redirected. It also helps in some cases when stderr is interleaved with stdout, depending on the details of the interleaving (this program has the usual null explicit support for syncing stderr with stdout). Return 1 instead of -1 after printing the "malloc failed" warning, since the return value is boolean. |
