ACCESS_MODE (ENUM)ΒΆ

TYPE ACCESS_MODE :

Access mode
File modes to open a file.

Note

For all *_PLUS modes be aware, that after reading from a file, writing can only be done after a call to SysFileGetPos or SysFileSetPos! If you call SysFileWrite right after SysFileRead, the file pointer could be on an invalid position!

Correct example:

SysFileRead();
SysFileGetPos();
SysFileWrite();
