char *strcat(char *dest, const char *src);
char *strncat(char *dest, const char *src, size_t n);
, dropping any trailing null
character in dest
. It is a str function
strncat is identical in functionality, except that it only appends the first n characters of src
Both functions return a pointer to dest.
At times like this, I realize how much I like.. hmm... essentially all other languages than C
. After all, in just about all other languages (PHP
, etc.) you can just say "string" + "foo" to get "stringfoo". But noooo, in C
, you get to handle the memory yourself
The uses for this function are both multifarious and fairly obvious, so I will not elaborate. In cases where you don't want to get a buffer overflow, you'd best use strncat (and set n intelligently).
