The DevT interface abstracts out some operations involving
the Unix dev_t type. This is intended to solve some portability
problems.
INTERFACE DevT;
IMPORT
OSError, TokScan, Utypes, Word;
TYPE
T = Utypes.dev_t;
PROCEDURE Decode(t: TEXT): T RAISES {TokScan.Error};
Encode a dev_t into a text string.
PROCEDURE Encode(READONLY dev: T): TEXT;
Decode a text string into a dev_t.
PROCEDURE Equal(READONLY a, b: T): BOOLEAN;
Test whether two dev_t values are equal.
PROCEDURE Hash(READONLY dev: T): Word.T;
Compute a hash value from a dev_t.
PROCEDURE Mknod(path: TEXT;
mode: Utypes.mode_t;
READONLY dev: T) RAISES {OSError.E};
Execute a Unix mknod call with the given arguments.
END DevT.
