How to use the strlcpy function in C ?

The strlcpy function copy a string into another string by limiting the number of copied characters. The prototype is:

size_t strlcpy(char *dst, const char *src, size_t size);

• The first parameter is the destination string (dst = destination)
• The second parameter is the string to copy (src = source)
• The third parameter is the number of characters to copy (size)

To use the strlcpy function, you have to include the bsd/string.h library:

#include <bsd/string.h>

Note that strlcpy is not a standard C function, while strncpy belongs to string.h.
