u-boot.git/include/linux/ctype.h, branch v2018.01 Unnamed repository; edit this file 'description' to name the repository. Add isblank 2011-10-17T20:25:34+00:00 Jason Hobbs jason.hobbs@calxeda.com 2011-08-23T11:06:52+00:00 93337abbfe2951c63a4e7b450da1848c6c69217f Existing ctype checks are implemented using a 256 byte lookup table, allowing each character to be in any of 8 character classes. Since there are 8 existing character classes without the blank class, I implemented isblank without using the lookup table. Since there are only two blank characters - tab and space - this is a more reasonable approach than doubling the size of the lookup table to accommodate one more class.
