This API is mainly for Terminal Emulator implementors, or those writing programs
|
||
|
|
that expect to interpreted by a terminal emulator and wish to determine the
|
||
|
|
printable width of a string on a Terminal.
|
||
|
|
|
||
|
|
Usually, the length of the string is equivalent to the number of cells it
|
||
|
|
occupies except that there are also some categories of characters which
|
||
|
|
occupy 2 or even 0 cells. POSIX-conforming systems provide wcwidth(3) and
|
||
|
|
wcswidth(3) of which this module's interface mirrors precisely.
