Checks if the character is lowercase
| Call | |
| #include <vv_sys.h> | |
| int ch_islower(ch) | |
|
UCHAR ch |
Character to be tested |
| Returns | |
| 1 | The character is lowercase |
| 0 | The character is not lowercase |
| Description
If the character code is less than 128, the standard C library function islower() is called to test the character. If the character code is greater than 128 and support for the extended character set is not enabled, the character is considered non-lowercase. If support for the extended character set is enabled (vv_extch.h is #included), the appropriate entry in the table _chsettbl[] is checked to determine if the character is lowercase. |
|
| Cautions
If the extended character set support is disabled (the default), all characters above 127 are considered non-lowercase. |
