Usage
The ifx_gl_iswprint() function tests whether wc is in the print character class according to the rules of the current locale. The print character class contains all characters that have a visual representation or are in the space class but not in the cntrl class.
All characters from the alpha, digit, punct, xdigit, and graph classes are also in this class. No characters in the cntrl class are in this class.
Locale information
The LC_CTYPE category of the current locale affects the behavior of this function because it defines the print character class.
