There are a number of video string functions to write strings to a window. Different functions allow you to have different levels of control over the way strings are written. For example, the simplest function, v_st(), writes a given string to a window at the location of the virtual cursor, using the window's attribute. v_stattpl(), on the other hand, allows you to specify the location to write the string and the attribute used to display it.
Most Vermont Views string output functions respect the current state of the window options. The exceptions are v_stattnop() and v_printf(). All string output functions handle tabs ('\t') and newline ('\n') characters.
Table 24.3: String Output Functions
| Function | Respects Options? | Description |
| v_st(stp, wnp) | Yes | Writes a string using the window attribute |
| v_statt(stp, att, wnp) | Yes | Writes a string using a new attribute |
| v_stpl(r, c, stp, wnp) | Yes | Writes a string using the window attribute at a specified place in the window |
| v_stattpl(r, c, stp, att, mv_type, wnp) | Yes | Writes a string and/or attribute starting at a specified place |
| v_stattnop(r, c, stp, att, mv_type, wnp) | No | Writes the string and/or attribute to the window at a specified place |
| v_printf(wnp, format_stp, args...) | Yes1 | Formats output and writes it to the window. |
1 Except for the scrolling quantity. The scrolling quantity is temporarily set to AS_NEEDED when doing formatted output.
Naming Tip: All functions that write to windows are preceded by "v_", for video.
