Embedded TCP/IP stack: fnet_strncat

Concatenates a string with part of another.

Parameters

dest	Pointer to the null-terminated string to append to.
src	Pointer to the null-terminated string to copy to the end of dest.
n	Maximum number of characters to be appended.

This function appends a copy of the string pointed to by src to the end of the string pointed to by dest. If the length of the src string is less than n, only the content up to the terminating null-character is copied.
The resulting string is null-terminated.
