From 07a3253de2c3f9bc2d96a351680ec72548dadd2d Mon Sep 17 00:00:00 2001 From: Joel Sherrill Date: Mon, 23 Nov 1998 19:07:58 +0000 Subject: Added base version of file system infrastructure. This includes a major overhaul of the RTEMS system call interface. This base file system is the "In-Memory File System" aka IMFS. The design and implementation was done by the following people: + Joel Sherrill (joel@OARcorp.com) + Jennifer Averett (jennifer@OARcorp.com) + Steve "Mr Mount" Salitasc (salitasc@OARcorp.com) + Kerwin Wade (wade@OARcorp.com) PROBLEMS ======== + It is VERY likely that merging this will break the UNIX port. This can/will be fixed. + There is likely some reentrancy/mutual exclusion needed. + Eventually, there should be a "mini-IMFS" description table to eliminate links, symlinks, etc to save memory. All you need to have "classic RTEMS" functionality is technically directories and device IO. All the rest could be left out to save memory. --- c/src/lib/libc/hosterr.c | 27 ++++++++++++++++----------- 1 file changed, 16 insertions(+), 11 deletions(-) (limited to 'c/src/lib/libc/hosterr.c') diff --git a/c/src/lib/libc/hosterr.c b/c/src/lib/libc/hosterr.c index a55e4a7e84..6c0308df3b 100644 --- a/c/src/lib/libc/hosterr.c +++ b/c/src/lib/libc/hosterr.c @@ -13,31 +13,36 @@ */ #include +#if defined(RTEMS_UNIX) #include -int host_errno(void); +int host_errno( void ); /* - * copy host errno, if any to thread aware errno, if any + * fix_syscall_errno + * + * copy host errno, if any to thread aware errno, if any */ -void fix_syscall_errno(void) +void fix_syscall_errno( void ) { - errno = host_errno(); + errno = host_errno(); } /* - * Get the host system errno, if any - * When using newlib (or possibly other libc's) on top of UNIX - * the errno returned by system calls may be unavailable due - * to trickery of making errno thread aware. - * This provides a kludge of getting at it. + * host_errno + * + * Get the host system errno, if any + * When using newlib (or possibly other libc's) on top of UNIX + * the errno returned by system calls may be unavailable due + * to trickery of making errno thread aware. + * This provides a kludge of getting at it. */ #undef errno extern int errno; int host_errno(void) { - return errno; + return errno; } - +#endif -- cgit v1.2.3
