#include <ctype.h>int isascii(int c);
The function or functions documented here may not be used safely in all application contexts with all APIs provided in the ChorusOS 5.0 product.
See API(5FEA) for details.
The isascii() function tests for an ASCII character, which is any character with a value less than or equal to 0177.
The isascii() function returns 1 if number is ASCII, otherwise 0.
The validity of the test is limited to the defaut locale. If another locale is currently in effect, the semantical correctness of the result is unspecified.
