SYNOPSIS
#include
char *strcat(char *dest, const char *src);
char *strncat(char *dest, const char *src, size_t n);
DESCRIPTION
strcat appends
src to
dest, 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.
NOTES
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,
JS,
basic,
PERL, etc.) you can just say "string" + "foo" to get "stringfoo". But noooo, in
C, you get to
handle the memory yourself. Yeehaw.
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).
