mchartable_map(3m17n) Version 1.5.5 mchartable_map(3m17n)

mchartable_map - Call a function for characters in a chartable.

int mchartable_map (MCharTable * table, void * ignore, void(*)(int, int, void *, void *) func, void * func_arg)

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 .

This function always returns 0.
