Detailed Description

Character classification routines.

Macro Definition 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.
