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.

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

EXAMPLES
     The following will point p to an allocated area of memory containing the
     nul-terminated string "foobar":

	   char *p;

	   if ((p = strdup("foobar")) == NULL) {
		   fprintf(stderr, "Out of memory.\n");
		   exit(1);
	   }

ERRORS
     The strdup() function may fail and set the external variable errno for
     any of the errors specified for the library function malloc(3).

SEE ALSO
     free(3), malloc(3), strcpy(3), strlen(3)

STANDARDS
     The strdup() function conforms to IEEE Std 1003.1-2001 (“POSIX.1”).

HISTORY
     The strdup() function first appeared in 4.4BSD.  The strndup() function
     was added in NetBSD 4.0.
