Flushes a file directly to disk.
int _commit( int fd );
- File descriptor referring to open file.
_commit returns 0 if the file was successfully flushed to disk. A return value of –1 indicates an error, and errno is set to EBADF, indicating an invalid file descriptor parameter.
The _commit function forces the operating system to write the file associated with fd to disk. This call ensures that the specified file is flushed immediately, not at the operating system's discretion.
