/*
 * This header file defines a set of POSIX errno values
 * that fits consistently into the COM error code namespace -
 * i.e. these error code values can be returned from COM object methods.
 * This header file just reuses the values defined in <oskit/error.h>,
 * so that programs using the oskit's minimal C library
 * can treat errno values and interface return codes interchangeably.
 *
 * One (probably the main) disadvantage of using these error codes
 * is that, since they don't start from around 0 like typical Unix errno values,
 * it's impossible to provide a Unix-style sys_errlist table for them.
 * However, they are fully compatible
 * with the POSIX-blessed strerror and perror routines,
 * and in any case the minimal C library
 * is not intended to support "legacy" applications directly -
 * for that purpose, a "real" C library would be more appropriate,
 * and such a C library would probably use more traditional errno values,
 * doing appropriate translation when interacting with COM interfaces.
