Remarks

strdup makes a duplicate of string s, obtaining space with a call to malloc. The allocated space is (strlen(s) + 1) bytes long. The user is responsible for freeing the space allocated by strdup when it is no longer needed.

Return value

strdup returns a pointer to the storage location containing the duplicated string, or returns null if space could not be allocated.

Example

#include <stdio.h>
#include <string.h>
#include <alloc.h>
int main (void)
{
   char *dup_str,  *string = "abode";
dup_str = strdup (string)
printf ("%s\n", dup_str);
free (dup_str);

return 0;
