CDClose (FUN) ¶ FUNCTION CDClose : DINT Close a character device file. InOut: Scope Name Type Comment Return CDClose DINT 0 on success Input hFile RTS_IEC_HANDLE File descriptor/handle, that was previously created with Open() pResult POINTER TO DINT Pointer to linux errno error code, 0 is ok

CDIoctl (FUN) ¶ FUNCTION CDIoctl : DINT Control a character device file. This function manipulates the underlying device parameters of special files. InOut: Scope Name Type Comment Return CDIoctl DINT 0 if ok or errno if failed. Input hFile RTS_IEC_HANDLE File descriptor/handle, that was previously created with Open() dRequest __XWORD Request id. dParameter __XWORD Request parameter. pResult POINTER TO DINT Pointer to linux errno error code

CDLseek (FUN) ¶ FUNCTION CDLseek : DINT Repositions the file offset of an open file. lseek() sets the file offset of hFile to the argument offset according to the directive whence InOut: Scope Name Type Comment Return CDLseek DINT the resulting offset location as measured in bytes from the beginning of the file or -1 if failed. Input hFile RTS_IEC_HANDLE File descriptor/handle, that was previously created with Open() offset DINT offset in bytes whence DINT one of the following flags: SEEK_SET: The file offset is set to offset bytes SEEK_CUR: The file offset is set to its current location plus offset bytes SEEK_END:The file offset is set to the size of the file plus offset pResult POINTER TO DINT Pointer to linux errno error code, 0 is ok

CDMmap (FUN) ¶ FUNCTION CDMmap : POINTER TO BYTE Map files or devices into memory. mmap() creates a new mapping in the virtual address space of the calling process. InOut: Scope Name Type Comment Return CDMmap POINTER TO BYTE pointer to the mapped area, or MAP_FAILED if failed. Input addr POINTER TO BYTE Pointer to starting address for the new mapping length UDINT Number of bytes mapped prot DINT Memory protection of the mapping. It is either PROT_NONE or the bitwise OR of one or more of the following flags: PROT_EXEC: Pages may be executed PROT_READ: Pages may be read PROT_WRITE: Pages may be written PROT_NONE: Pages may not be accessed flags DINT one of the following flags MAP_SHARED: Share this mapping MAP_SHARED_VALIDATE: This flag provides the same behavior as MAP_SHARED except that MAP_SHARED mappings ignore unknown flags in flags MAP_PRIVATE: Create a private copy-on-write mapping Optional flags for mmap: See linux man page for Details hFile RTS_IEC_HANDLE File descriptor of the file to be mapped offset DINT Offset in the file (or other object) where mapping starts pResult POINTER TO DINT Pointer to linux errno error code, 0 is ok
