create a duplicate of a string
#include <string.h> char *strdup( const char *src ); char *_strdup( const char *src ); char __far *_fstrdup( const char __far *src );
The strdup() and _fstrdup() functions create a duplicate of the string pointed to by src, and returns a pointer to the new copy. For strdup(), the memory for the new string is obtained by using the malloc() function, and can be freed using the free() function. For _fstrdup(), the memory for the new string is obtained by using the _fmalloc() function, and can be freed using the _ffree() function.
The _strdup() function is identical to strdup(). Use _strdup() for ANSI naming conventions.
The _fstrdup() function is a data-model-independent form of the strdup() function that accepts far pointer arguments. It is most useful in mixed memory model applications.

_strdup() conforms to ANSI naming conventions.
