Cross platform interface to POSIX function strdup().
|
|
|
|
The fl_strdup() function returns a pointer to a new string which is
|
|
a duplicate of the string 's'. Memory for the new string is obtained
|
|
with malloc(3), and can be freed with free(3).
|

|
|
Implementation:
|
|
- POSIX: strdup()
|
|
- WinAPI: _strdup()
