Typedef Documentation

typedef off_t _libio_off_t

Hide libio API lossage.

The libio interface changed after glibc-2.1.3 to pass the seek offset argument as a pointer rather than as an off_t. The snarl below defines typedefs to isolate the lossage. API unchanged.

typedef struct _FDSTACK_s FDSTACK_t

typedef { ... } * FDSTAT_t

Cumulative statistics for a descriptor.
