10 | /* | |
11 | * This version of ctype.h provides a standardised and platform | |
12 | * independent implementation that supports seven bit ASCII characters. | |
13 | * The specific intent is to not pass extended ASCII characters (> 127) | |
14 | * even if the host operating system would. | |
15 | * | |
16 | * There is EBCDIC support included for machines which use this. However, | |
17 | * there are a number of concerns about how well EBCDIC is supported | |
18 | * throughout the rest of the source code. Refer to issue #4154 for | |
19 | * details. | |
