Query about rename() prototype?
I am using NetBSD sources for my system and I have a question
about rename() function prototype.
I have seen the prototype of rename() is added the following two places:
% cat src/include/unistd.h
* X/Open Portability Guide <= Issue 3
#if defined(_XOPEN_SOURCE) && (_XOPEN_SOURCE - 0) <= 3
int rename(const char *, const char *) __RENAME(__posix_rename);
% cat src/include/stdio.h
#if defined(_POSIX_C_SOURCE) || defined(_XOPEN_SOURCE)
int rename (const char *, const char *) __RENAME(__posix_rename);
int rename (const char *, const char *);
From the POSIX specifications link below:
It is noticed that the prototype should be in <stdio.h>
I understand that if my application is _XOPEN_SOURCE complaint
then i have the prototype in <unistd.h> as well.
My query is:
In my application to which prototype should i refer from stdio.h or
unistd.h? (Do i need to modify my application?)
Thanks in advance!!
thanks and regards,
