File Input and Output Routines
These API routines allow you to directly create and manipulate files.
- _FCHSize( ) API Library Routine
Sets the file size on disk to the specified length. The specified length may extend or truncate the file.
- _FClose( ) API Library Routine
Terminates access to a file. Any buffers that have been modified while the buffer is open are automatically flushed to disk.
- _FCopy( ) API Library Routine
Attempts to copy len bytes from position spos in file sc to position dpos in file dc.
- _FCreate( ) API Library Routine
Assigns a Visual FoxPro channel to a new file.
- _FEOF( ) API Library Routine
Returns True if the file is currently at the end of file; otherwise, returns False.

Returns the last file operation error recorded for any channel.
- _FFlush( ) API Library Routine
Ensures that all modified buffers in memory have been flushed out to disk.
- _FGets( ) API Library Routine
Reads a single line of maxlen length, delimited with a carriage return, from a file.
- _FOpen( ) API Library Routine
Assigns a Visual FoxPro channel to an existing file.
- _FPuts( ) API Library Routine
Writes a null-terminated string to a file, followed by a carriage return/line feed pair.
- _FRead( ) API Library Routine
Reads exactly length bytes from a file into buffer.
- _FSeek( ) API Library Routine
Moves the file pointer to a new location as specified by position and mode.
- _FWrite( ) API Library Routine
Writes exactly length bytes from your buffer to a file. No terminator is added to the file.
