## 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.

Definition at line 48 of file svn_ctype.h.
