tickit_stringpos_limit_bytes3
Set limit fields in string position counters
Usage
#include <tickit.h> void tickit_stringpos_limit_bytes(TickitStringPos *pos, size_t bytes); void tickit_stringpos_limit_codepoints(TickitStringPos *pos, int codepoints); void tickit_stringpos_limit_graphemes(TickitStringPos *pos, int graphemes); void tickit_stringpos_limit_columns(TickitStringPos *pos, int columns); void tickit_stringpos_limit_none(TickitStringPos *pos); #define INIT_TICKIT_STRINGPOS_LIMIT_BYTES(bytes) #define INIT_TICKIT_STRINGPOS_LIMIT_CODEPOINTS(codepoints) #define INIT_TICKIT_STRINGPOS_LIMIT_GRAPHEMES(grahpemes) #define INIT_TICKIT_STRINGPOS_LIMIT_COLUMNS(columns) #define INIT_TICKIT_STRINGPOS_LIMIT_NONE

Overview
The first four of these functions each set one of the counter fields in pos to the given value, and the other three to -1. This is useful to create a limit counter to stop tickit_utf8_count(3) or tickit_utf8_countmore(3) at the given position. The final function initialises all four fields to -1.
Each is also available as a macro which can be used to initialise a new TickitStringPos variable.
TickitStringPos limit = INIT_TICKIT_STRINGPOS_LIMIT_BYTES(b);
Return value
The functions all return no value. The macros expand to a struct initialiser expression.
