The function opens the specified file for reading.
Declaration
INT %FIO_OpenRead(
TEXT in fileName
[,BOOL in utf8 = @FALSE | ,TEXT in encoding = "@APP_DEFAULT@"]
)
Parameters
fileName
Name
of the file to open.
utf8
Optional parameter of Boolean type. If it is not
written its alternate value is
@FALSE.
If the value is @TRUE, the file is supposed to be text-based
and its content is encoded in UTF-8. When file
encoded by UTF8 is being read a possible BOM is omitted (characters
0xEF, 0xBB, 0xBF).
Zero - cannot open the file, nonzero - file opened.
Value of the parameter is used later when calling other %FIO_*
functions, which need it. Value is valid within the ESL script instance, the function was called from.
Note
Having finished work with the file, it must be
closed by calling the function %FIO_Close.
If execution of ESL script is terminated early, the
process D2000 EventHandler
will automatically close all open files.
