SYNOPSIS

     #include <string.h>

     char *
     strdup(const char *str);

DESCRIPTION

     The strdup() function allocates sufficient memory for a copy of the
     string str, does the copy, and returns a pointer to it.  The pointer may
     subsequently be used as an argument to the function free(3).

     If insufficient memory is available, NULL is returned and errno is set to
     ENOMEM.

SEE ALSO

     free(3), malloc(3)
