This PR replaces the stub for the
access
system call in the zigux mlibc sysdeps with a basic implementation that returns 0 if the file exists. It ignores file permissions, but fully implementingaccess
should be trivial when file permissions are implemented in zigux by simply computing the correct return value based onstatbuf.st_mode
.I wasn't able to get zig and jinx working on my system to test if this works (or even compiles), but in theory, this should resolve #2.
