Detailed Description

Character classification routines.

Since:

New in 1.2.

Definition in file svn_ctype.h.

Define Documentation

#define svn_ctype_test	(		c,
			flags
	)		(0 != (svn_ctype_table[(unsigned char)(c)] & (flags)))

Check if c is in the character class described by flags.

The flags is a bitwise-or combination of SVN_CTYPE_* constants. Uses svn_ctype_table.
