STRDUP(3) BSD Library Functions Manual STRDUP(3)NAMEstrdup — save a copy of a string
strdup(const char *str);
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.
The strdup() function first appeared in 4.4BSD.
