From b48327d357e0818d1a6ae2a064cfa7d1567e1242 Mon Sep 17 00:00:00 2001 From: Nicholas Noll Date: Sun, 5 Dec 2021 15:17:44 -0800 Subject: feat(huge): huge refactor (in progress). Commented out libc includes to uncover all explicit dependencies. A large fraction has now been ported over (no testing). I did not port over the command line tools, such as the rc shell. These will be done independently - as of now I just want the library to stand independent. Compilation currently fails due to the lack of math functions. --- src/cmd/core/cat.c | 14 ++++++++------ 1 file changed, 8 insertions(+), 6 deletions(-) (limited to 'src/cmd/core/cat.c') diff --git a/src/cmd/core/cat.c b/src/cmd/core/cat.c index e9b770b..aeed1be 100644 --- a/src/cmd/core/cat.c +++ b/src/cmd/core/cat.c @@ -11,15 +11,15 @@ usage(void) static void cat(int fd, char *s) { - long n; + intptr nr, nw; char buf[8192]; - while((n=read(fd, buf, sizeof(buf)))>0){ - if(write(1, buf, n) != n) + while(!(sys·read(fd, buf, sizeof(buf), &nr))){ + if(sys·write(1, buf, nr, &nw) || nr != nw) fmt·panic("write error copying %s: %r", s); } - if(n<0) + if(nr<0) fmt·panic("error reading %s: %r", s); } @@ -40,12 +40,14 @@ main(int argc, char *argv[]) } while(argc-- > 0){ - if((fd = open(*argv, O_RDONLY))<0) + if(sys·open(*argv, sys·ORead, 0, &fd)) fmt·panic("can't open %s: %r", *argv); cat(fd, *argv); - close(fd); + sys·close(fd); argv++; } + + return 0; } -- cgit v1.2.1
