Description

The getwidth() function reads the character class table for the current locale, generated by wchrtbl() (see chrtbl(1M) ) to get information on the supplementary codesets. getwidth() sets this information into the struct eucwidth_t. This struct is defined in <euc.h> and has the following members:

    short int _eucw1,_eucw2,_eucw3;
    short int _scrw1,_scrw2,_scrw3;
    short int _pcw;
    char _multibyte;

Codeset width values for supplementary codesets 1, 2, and 3 are set in _eucw1, _eucw2, and _eucw3, respectively. Screen width values for supplementary codesets 1, 2, and 3 are set in _scrw1, _scrw2, and _scrw3, respectively.

The width of Extended Unix Code (EUC) Process Code is set in _pcw. The _multibyte entry is set to 1 if multibyte characters are used, and set to 0 if only single-byte characters are used.
