TICKIT_RENDERBUFFER_TEXT(3) Library Functions Manual TICKIT_RENDERBUFFER_TEXT(3) NAME tickit_renderbuffer_text, tickit_renderbuffer_text_at - create text regions SYNOPSIS #include <tickit.h> int tickit_renderbuffer_text(TickitRenderBuffer *rb, const char *text); int tickit_renderbuffer_textn(TickitRenderBuffer *rb, const char *text, size_t len); int tickit_renderbuffer_textf(TickitRenderBuffer *rb, const char *fmt, ...); int tickit_renderbuffer_vtextf(TickitRenderBuffer *rb, const char *fmt, va_list args); int tickit_renderbuffer_text_at(TickitRenderBuffer *rb, int line, int col, const char *text); int tickit_renderbuffer_textn_at(TickitRenderBuffer *rb, int line, int col, const char *text, size_t len); int tickit_renderbuffer_textf_at(TickitRenderBuffer *rb, int line, int col, const char *fmt, ...); int tickit_renderbuffer_vtextf_at(TickitRenderBuffer *rb, int line, int col, const char *fmt, va_list args); Link with -ltickit. DESCRIPTION tickit_renderbuffer_text() creates a text region that starts at the current virtual cursor position, containing the given text string and set to the current pen. tickit_renderbuffer_textn() creates a text region of at most len bytes. It returns the number of columns that the text string occupies. tickit_renderbuffer_textf() and tickit_renderbuffer_vtextf() take a format string in the style of sprintf(3) to create formatted text from either a list of arguments or a va_list. These functions will update the virtual cursor position. tickit_renderbuffer_text_at(), tickit_renderbuffer_textn_at(), tickit_ren- derbuffer_textf_at() and tickit_renderbuffer_vtextf_at() create a text re- gion at the given position, and otherwise operate analogously to their non-_at counterpart. These functions do not use or update the virtual cur- sor position. Calls to any of these functions allocate storage owned by the TickitRender- Buffer instance itself to store the strings. This storage is released again by tickit_renderbuffer_reset(3), the implicit reset that happens at the end of tickit_renderbuffer_flush_to_term(3), or when every cell that was origi- nally part of the region has been overwritten with other content. RETURN VALUE These functions return an integer giving the number of columns the new re- gion occupies.
