Function avr_libc::strdup

pub unsafe extern "C" fn strdup(s1: *const i8) -> *mut i8

\ingroup avr_string \fn char *strdup(const char *s1) \brief Duplicate a string.

The strdup() function allocates memory and copies into it the string addressed by s1, including the terminating null character.

\warning The strdup() function calls malloc() to allocate the memory for the duplicated string! The user is responsible for freeing the memory by calling free().

\returns The strdup() function returns a pointer to the resulting string dest. If malloc() cannot allocate enough storage for the string, strdup() will return NULL.

\warning Be sure to check the return value of the strdup() function to make sure that the function has succeeded in allocating the memory!
