WCSDUP(3)               NetBSD Library Functions Manual              WCSDUP(3)

NAME
     wcsdup -- save a copy of a string

LIBRARY
     Standard C Library (libc, -lc)

SYNOPSIS
     #include <wchar.h>

     wchar_t *
     wcsdup(const wchar_t *str);

DESCRIPTION
     The wcsdup() function allocates sufficient memory for a copy of the wide
     character 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.

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

           wchar_t *p;

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

ERRORS
     The wcsdup() 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), strdup(3)

HISTORY
     The wcsdup() function first appeared in NetBSD 4.0.
