|---|---|
| More convenient |
"Additionally if you have strdup then it is much more convenient than strlen + malloc + strcpy with identical result including the same obligation to free the allocated storage when you no longer need it" from question "How do I store my substring between strtok tokens in C?" |
| Cleaner |
"As i noted in comments however if you re willing to rely on posix s strdup then that s cleaner than strlen + malloc + and has the same semantics you take responsibility for freeing the memory allocated for the copy" from question "Conditional jump or move depends on uninitialised value(s) in C" |
