6 .TH GETWIDTH 3C "Dec 20, 1996"
8 getwidth \- get codeset information
15 \fBvoid\fR \fBgetwidth\fR(\fBeucwidth_t *\fR\fIptr\fR);
21 The \fBgetwidth()\fR function reads the character class table for the current
22 locale to get information on the supplementary codesets. \fBgetwidth()\fR sets
23 this information into the struct \fBeucwidth_t\fR. This struct is defined in
24 <\fBeuc.h\fR> and has the following members:
28 short int _eucw1,_eucw2,_eucw3;
29 short int _scrw1,_scrw2,_scrw3;
37 Codeset width values for supplementary codesets 1, 2, and 3 are set in
38 \fB_eucw1\fR, \fB_eucw2\fR, and \fB_eucw3\fR, respectively. Screen width values
39 for supplementary codesets 1, 2, and 3 are set in \fB_scrw1\fR, \fB_scrw2\fR,
40 and \fB_scrw3\fR, respectively.
43 The width of Extended Unix Code (EUC) Process Code is set in \fB_pcw\fR. The
44 \fB_multibyte\fR entry is set to \fB1\fR if multibyte characters are used, and
45 set to \fB0\fR if only single-byte characters are used.
49 See \fBattributes\fR(5) for descriptions of the following attributes:
57 ATTRIBUTE TYPE ATTRIBUTE VALUE
59 MT-Level MT-Safe with exceptions
65 \fBeuclen\fR(3C), \fBsetlocale\fR(3C), \fBattributes\fR(5)
69 The \fBgetwidth()\fR function can be used safely in a multithreaded
70 application, as long as \fBsetlocale\fR(3C) is not being called to change the
74 The \fBgetwidth()\fR function will only work with \fBEUC\fR locales.
