Defined in header
char *strndup(const char *str, size_t size);
|(dynamic memory TR)|
Returns a pointer to a null-terminated byte string, which contains copies of at most
size bytes from the string pointed to by
str. If the null terminator is not encountered in the first
size bytes, it is added to the duplicated string.
The returned pointer must be passed to free to avoid a memory leak.
If an error occurs, a null pointer is returned and errno may be set.
As all functions from Dynamic Memory TR,
strndup is only guaranteed to be available if __STDC_ALLOC_LIB__ is defined by the implementation and if the user defines __STDC_WANT_LIB_EXT2__ to the integer constant 1 before including
