CDMunmap (FUN) ¶ FUNCTION CDMunmap : DINT Unmap files or devices into memory. The munmap() system call deletes the mappings for the specified address range. InOut: Scope Name Type Comment Return CDMunmap DINT 0 on success, -1 if failed. Input addr POINTER TO BYTE Pointer to starting address length UDINT Number of bytes mapped pResult POINTER TO DINT Pointer to linux errno error code, 0 is ok

CDOpen (FUN) ¶ FUNCTION CDOpen : RTS_IEC_HANDLE Open a character device file. Given a pathname for a file, open() returns a file descriptor handle for use in subsequent system calls (read(), write(), ioctl(), etc.). InOut: Scope Name Type Comment Return CDOpen RTS_IEC_HANDLE Handle or RTS_INVALID_HANDLE if failed. Input szFile STRING(80) File name. File name must be an absolute path to the file. Path entries must be separated with a ‘/’ and not with a ‘"! dFlags DINT Requested ACCESS_MODE for fileaccess: dwFlags must include one of the following flags: O_RDONLY: read-only access O_WRONLY: write-only access O_RDWR: read/write access Optional flags for fileaccess: See linux man page for Details pResult POINTER TO DINT Pointer to linux errno error code, 0 is ok

CDRead (FUN) ¶ FUNCTION CDRead : DINT Read from a character device file. Read() attempts to read up to count bytes from file handle hFile into the buffer starting at buf. InOut: Scope Name Type Comment Return CDRead DINT Nr of Bytes copied. Input hFile RTS_IEC_HANDLE File descriptor/handle, that was previously created with Open() pbyBuffer POINTER TO BYTE Buffer to copy bytes into. udCount UDINT Nr of bytes to copy. pResult POINTER TO DINT Pointer to linux errno error code, 0 is ok

CDWrite (FUN) ¶ FUNCTION CDWrite : DINT Write to a character device file. Write() attempts to write up to count bytes from file handle hFile into the buffer starting at buf. InOut: Scope Name Type Comment Return CDWrite DINT Nr of Bytes copied. Input hFile RTS_IEC_HANDLE File descriptor/handle, that was previously created with open() pbyBuffer POINTER TO BYTE Buffer to copy bytes from. udCount UDINT Nr of bytes to copy. pResult POINTER TO DINT Pointer to linux errno error code, 0 is ok
