NAME¶
mchartable_map - Call a function for characters in a chartable.
SYNOPSIS¶
int
mchartable_map (
MCharTable *
table, void *
ignore, void(*)(int,
int, void *, void *)
func, void *
func_arg)
DESCRIPTION¶
Call a function for characters in a chartable. The mchartable_map() function
calls function func for characters in chartable table
. No function
call occurs for characters that have value ignore in table
. Comparison
of ignore and character value is done with the operator ==
. Be careful
when you use string literals or pointers.
Instead of calling func for each character, mchartable_map() tries to optimize
the number of function calls, i.e. it makes a single function call for a chunk
of characters when those consecutive characters have the same value.
No matter how long the character chunk is, func is called with four arguments;
from
, to
, val
, and arg
. from and to (both
inclusive) defines the range of characters that have value val
. arg is
the same as func_arg
.
RETURN VALUE¶
This function always returns 0.
