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.

Definition at line 34 of file rpmio.h.

typedef struct FDIO_s* FDIO_t

Definition at line 40 of file rpmio.h.

typedef enum fdOpX_e fdOpX

Identify per-desciptor I/O operation statistics.

Enumeration Type Documentation

enum fdOpX_e

Identify per-desciptor I/O operation statistics.

FDSTAT_READ	Read statistics index.
FDSTAT_WRITE	Write statistics index.
FDSTAT_SEEK	Seek statistics index.
FDSTAT_CLOSE	Close statistics index
FDSTAT_DIGEST	Digest statistics index.
FDSTAT_MAX
