Overview
The strdup() function allocates sufficient memory for a copy of the string str, does the copy, and returns a pointer to it. The memory is allocated with malloc(3) and should be released with free(3) when no longer needed.
The strndup() function copies at most len characters from the string str always NUL terminating the copied string.
The strdupa() function is identical to strdup() but allocates the memory with alloca(3). Similarly, the strndupa() function is identical to strndup(), but allocates the memory with alloca(3).
Return values
If insufficient memory is available, NULL is returned and errno is set to ENOMEM. Otherwise, the strdup() family of functions return a pointer to the copied string.
