2000-05-05 Michael Snyder <msnyder@seadog.cygnus.com>
* procfs.c: Cleanup of procfs tracing. Move defines and prototypes to proc-utils.h * proc-utils.h: Define tracing macros. Declare trace functions. * proc-api.c: Make procfs tracing a runtime option. (prepare_to_trace): New function, abstracted out of several places. Open a trace file if one is required. (ioctl_with_trace, write_with_trace, open_with_trace, close_with_trace, wait_with_trace, lseek_with_trace): Report errno if an error occurs in a system call. (write_with_trace): Make 2nd arg void *, to agree with write.
