NAME

       nng_strdup - duplicate string

SYNOPSIS

           #include <nng/nng.h>

           char *nng_strdup(const char *src);

DESCRIPTION

       The nng_strdup() duplicates the string src and returns it.

       This is logically equivalent to using nng_alloc() to allocate a region of memory of
       strlen(s) + 1 bytes, and then using strcpy() to copy the string into the destination
       before returning it.

       The returned string should be deallocated with nng_strfree(), or may be deallocated using
       the nng_free() using the length of the returned string plus one (for the NUL terminating
       byte).

           Important
           Do not use the system free() or similar functions to deallocate the string, since
           those may use a different memory arena!

RETURN VALUES

       This function returns the new string on success, and NULL on failure.

ERRORS

       No errors are returned, but a NULL return value should be treated the same as NNG_ENOMEM.
