The mcharset_map_chars() function calls .ft B func .ft R for all the characters in the charset named .ft B charset_name\fP\&. A call is done for a chunk of consecutive characters rather than character by character\&. .PP \fBfunc .ft R receives three arguments: .ft B from\fP, .ft R .ft B to\fP, .ft R and .ft B arg\fP\&. .ft B from .ft R and .ft B to .ft R specify the range of character codes in .ft B charset\fP\&. .ft B arg .ft R is the same as .ft B func_arg\fP\&. .PP .SH RETURN VALUE .PP .RS 4 If the operation was successful, mcharset_map_chars() returns 0\&. Otherwise, it returns \-1 and assigns an error code to the external variable .ft B merror_code\fP\&. .br .RE .PP .SH ERRORS .PP .RS 4 \fCMERROR_CHARSET .ft R .br .RE .PP .SH COPYRIGHT Copyright (C) 2001 Information\-technology Promotion Agency (IPA) .br Copyright (C) 2001\-2011 National Institute of Advanced Industrial Science and Technology (AIST) .br Permission is granted to copy, distribute and/or modify this document under the terms of the GNU Free Documentation License .
