STRDUP(3)		 BSD Library Functions Manual		     STRDUP(3)

NAME
     strdup, strndup — save a copy of a string

LIBRARY
     Standard C Library (libc, -lc)

SYNOPSIS
     #include <string.h>

     char *
     strdup(const char *str);

     char *
     strndup(const char *str, size_t len);

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.

     The strndup() function copies at most len characters from the string str
     always NUL terminating the copied string.

SEE ALSO
     free(3), malloc(3), wcsdup(3)

HISTORY
     The strdup() function first appeared in 4.4BSD.  The strndup() function
     was added in FreeBSD 7.2.
