Defines ioctl operations and data types for handling EUC code sets.
The eucioctl.h file contains information used for handling Extended UNIX Code (EUC) multibyte code sets. It consists of ioctl operations and the related data structure.
The eucioc structure contains the following fields:
| eucw[4] | Specifies the memory width of the code set. It indicates the number of bytes used to store the multibyte characters of each of the four classes. |
| scrw[4] | Specifies the screen width of the code set. It indicates the number of columns used to display the multibyte characters of each of the four classes. |
This structure is used in the following ioctl operations:
| EUC_WGET | Returns the EUC character widths. The eucioc structure is filled with the memory and screen widths of the current EUC code set. |
| EUC_WSET | Sets the EUC character widths. The eucioc structure is used to set the memory and screen widths of the current EUC code set. |
