| | | | | | | | | | | | | netent. - Change 1st argument of getnetbyaddr() to an uint32_t on 64 bit arch as well to confirm to POSIX-2001. These changes break ABI compatibility on 64 bit arch. There is similar padding issue for ai_addrlen of struct addrinfo. However, it is leaved as is for now. Discussed on: arch@, standards@ and current@ X-MFC after: never

| | | | | | | | | | | | | | | | RFC 2553. In XNS5.2, and subsequently in POSIX-2001 and RFC 3493, it was changed to a socklen_t. And, the n_net of a struct netent used to be an unsigned long integer. In XNS5, and subsequently in POSIX-2001, it was changed to an uint32_t. To accomodate for this while preserving ABI compatibility with the old interface, we need to prepend or append 32 bits of padding, depending on the (LP64) architecture's endianness. - Correct 1st argument of getnetbyaddr() to uint32_t on 32 bit arch. Stay as is on 64 bit arch for ABI backward compatibility for now. Reviewed by: das, peter MFC after: 2 weeks

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | adding (weak definitions to) stubs for some of the pthread functions. If the threads library is linked in, the real pthread functions will pulled in. Use the following convention for system calls wrapped by the threads library: __sys_foo - actual system call _foo - weak definition to __sys_foo foo - weak definition to __sys_foo Change all libc uses of system calls wrapped by the threads library from foo to _foo. In order to define the prototypes for _foo(), we introduce namespace.h and un-namespace.h (suggested by bde). All files that need to reference these system calls, should include namespace.h before any standard includes, then include un-namespace.h after the standard includes and before any local includes. <db.h> is an exception and shouldn't be included in between namespace.h and un-namespace.h namespace.h will define foo to _foo, and un-namespace.h will undefine foo. Try to eliminate some of the recursive calls to MT-safe functions in libc/stdio in preparation for adding a mutex to FILE. We have recursive mutexes, but would like to avoid using them if possible. Remove uneeded includes of <errno.h> from a few files. Add $FreeBSD$ to a few files in order to pass commitprep. Approved by: -arch
