Public Attributes
Mode	mode
	Open mode (read, write, append, etc.). See FileOpen::Mode for more details.
bool	inheritable = false
	Set to true to make the file visible to child processes.
bool	blocking = true
	Set to false if file will be used for Async I/O (see Async)
bool	sync = false
	Set to true to open file in synchronous mode, bypassing local file system cache.
bool	exclusive = false
	Set to true to fail if the file already exists (like 'x' flag in fopen)

Detailed Description

Member Enumeration Documentation

Mode

enum SC::FileOpen::Mode : uint8_t

Indicates the mode in which the file should be opened (read, write, append, etc.)

Enumerator
Read	r Open for reading. An error occurs if the file does not exist.
ReadWrite	r+ Open for reading and writing. An error occurs if the file does not exist.
Append	a Open for appending. The file is created if it does not exist.
AppendRead	a+ Open for reading and appending. The file is created if it does not exist.
Write	w Open for writing. The file is created (if it does not exist) or truncated (if it exists).
WriteRead	w+ Open for reading and writing. The file is created (if it does not exist) or truncated.
