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.

Enumerator:
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 

Definition at line 151 of file rpmio.h.
