_commit

Flushes a file directly to disk.

Syntax

int _commit(
   int fd
);

Parameters

fd
File descriptor referring to the open file.

Return Value

_commit returns 0 if the file was successfully flushed to disk. A return value of -1 indicates an error.

Remarks

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.

If fd is an invalid file descriptor, the invalid parameter handler is invoked, as described in Parameter Validation. If execution is allowed to continue, the function returns -1 and errno is set to EBADF.

Requirements

Routine Required header Optional headers
