strncat Appends characters to a string.
#include
char *strncat(
char *s1, /* destination string */
const char *s2, /* source string */
size_t n /* source length */
)
Description
Arguments
Return Value
Error Codes
This function appends up to n characters from one string (s2) to the end of another
string (s1). The first character in the source string overwrites the terminating null
character in the destination string. A null character and characters that follow it in
the source string are not appended.
The resulting string is always null terminated. If the length of the source string is
greater than the number of characters specified in the call, only the specified
number of characters (not including the null termination character) is appended.
If copying takes place between objects that overlap, the behavior is undefined.
s1 Points to the destination string.
s2 Points to the source string.
n Specifies the number of characters to append.
This function returns the value of s1.
None.
