spt_fstatz(2) OSS System Calls Reference Manual
NAME
spt_fstatz - Provides information about an open file (serializes I/O operations on an open file)
LIBRARY
H-series and J series OSS processes: /G/system/zdllnnn/zsptdll
SYNOPSIS
#include <sys/types.h> /* optional except for POSIX.1 */
#include <sys/stat.h>
#include <spthread.h>
int spt_fstatz(
int filedes,
struct stat *buffer);
PARAMETERS
filedes Specifies an open file descriptor obtained from a successful call to the accept(),
creat(), creat64(),dup(), dup2(), fcntl(), open(), open64(), pipe(), socket(),
or socketpair() function.
buffer Points to a stat structure, into which information is placed about the file. The stat
structure is described in the sys/stat.h header file.
DESCRIPTION
The spt_fstatz() function is a thread-aware version of the fstat() function.
The spt_fstatz() function obtains information about the open file associated with the filedes
parameter.
The file information is written to the area specified by the buffer parameter, which is a pointer to
a stat structure. For J06.11 and later J-series RVUs and H06.22 and later H-series RVUs, the
stat structure uses this definition from the sys/stat.h header file:
struct stat {
dev_t st_dev;
ino_t st_ino;
mode_t st_mode;
nlink_t st_nlink;
unsigned int st_acl:1;
unsigned int __filler_1:7;
unsigned int st_fileprivs:8; /* File privileges */
uid_t st_uid;
gid_t st_gid;
#if _FILE_OFFSET_BITS != 64 || _TANDEM_ARCH_ == 0
mode_t st_basemode; /* Permissions with original group perms */
#endif
dev_t st_rdev;
off_t st_size;
time_t st_atime;
time_t st_mtime;
time_t st_ctime;
#if _FILE_OFFSET_BITS == 64 && _TANDEM_ARCH_ != 0
mode_t st_basemode; /* Permissions with original group perms */
#endif
int64_t st_reserved[3];
};
