FileIsEnding
FileIsEnding
Defines the end of a file in the process of reading.
bool FileIsEnding(
int file_handle // File handle
);Parameters
- file_handle
[in] File descriptor returned by FileOpen().
Return Value
The function returns true if the file end has been reached in the process of reading or moving of the file pointer.
Note
To define the end of the file, the function tries to read the next string from it. If the string does not exist, the function returns true, otherwise it returns false.
Example:
//--- show the window of input parameters when launching the script
#property script_show_inputs
//--- input parameters
input string InpFileName="file.txt"; // file name
input string InpDirectoryName="Data"; // directory name
input int InpEncodingType=FILE_ANSI; // ANSI=32 or UNICODE=64
//+------------------------------------------------------------------+
//| Script program start function |
//+------------------------------------------------------------------+
void OnStart()
{
//--- print the path to the file we are going to use
PrintFormat("Working %s\\Files\\ folder",TerminalInfoString(TERMINAL_DATA_PATH));
//--- reset the error value
ResetLastError();
//--- open the file for reading (if the file does not exist, the error will occur)
int file_handle=FileOpen(InpDirectoryName+"//"+InpFileName,FILE_READ|FILE_TXT|InpEncodingType);
if(file_handle!=INVALID_HANDLE)
{
//--- print the file contents
while(!FileIsEnding(file_handle))
Print(FileReadString(file_handle));
//--- close the file
FileClose(file_handle);
}

PrintFormat("Error, code = %d",GetLastError());
