| char *strcat( char *dest, const char *src ); |
(until C99) | |
| char *strcat( char *restrict dest, const char *restrict src ); |
(since C99) | |
Appends a byte string pointed to by src to a byte string pointed to by dest. The resulting byte string is null-terminated.
The destination byte string must be large enough for the contents of both str and dest and the terminating null character.
The behavior is undefined if the strings overlap.

Parameters
