Typedef Documentation

◆ FDIO_t

typedef const struct FDIO_s* FDIO_t

Definition at line 25 of file rpmio.h.

◆ fdOpX

typedef enum fdOpX_e fdOpX

Identify per-desciptor I/O operation statistics.

Enumeration Type Documentation

Function Documentation

◆ Fclose()

int Fclose ( FD_t  fd)

fclose(3) clone.

◆ Fcntl()

int Fcntl ( FD_t  fd,
int  op,
void *  lip 
)

fcntl(2) clone.

◆ fdDup()

FD_t fdDup ( int  fdno)

◆ Fdescr()

const char* Fdescr ( FD_t  fd)

Get informative description (eg file name) from fd for diagnostic output.

◆ fdFree()

FD_t fdFree ( FD_t  fd)

◆ fdLink()

FD_t fdLink ( FD_t  fd)

◆ fdOp()

rpmop fdOp ( FD_t  fd,
fdOpX  opx 
)

◆ Fdopen()

FD_t Fdopen ( FD_t  ofd,
const char *  fmode 
)

◆ fdSize()

off_t fdSize ( FD_t  fd)

◆ Ferror()

int Ferror ( FD_t  fd)

ferror(3) clone.

◆ Fflush()

int Fflush ( FD_t  fd)

fflush(3) clone.

◆ Fileno()

int Fileno ( FD_t  fd)

fileno(3) clone.

◆ Fopen()

FD_t Fopen ( const char *  path,
const char *  fmode 
)

fopen(3) clone.

◆ Fread()

ssize_t Fread ( void *  buf,
size_t  size,
size_t  nmemb,
FD_t  fd 
)

Like fread(3) but with read(3)-style return values.

◆ Fseek()

int Fseek ( FD_t  fd,
off_t  offset,
int  whence 
)

fseek(3) clone.

◆ Fstrerror()

const char* Fstrerror ( FD_t  fd)

strerror(3) clone.

◆ Ftell()

off_t Ftell ( FD_t  fd)

ftell(3) clone.

◆ Fwrite()

ssize_t Fwrite ( const void *  buf,
size_t  size,
size_t  nmemb,
FD_t  fd 
)

Like fwrite(3) but with write(3)-style return values.

◆ ufdCopy()

off_t ufdCopy ( FD_t  sfd,
FD_t  tfd 
)
