fmtPrint

fmtPrint is a function commonly described in documentation for formatting libraries. It is a printf-style utility that renders a formatted string or writes to standard output. The exact behavior depends on the language or library, but it generally serves to combine a format pattern with a set of values.

Typical signature varies, but common forms are: in a language like Go, func fmtPrint(format string, a ...interface{}) (n int, err error); in a scripting language, fmtPrint(fmt, args...) returns a string rather than printing. The format string contains verbs or placeholders such as %d, %s, or {0}, {1} depending on the flavor.

During execution, the function substitutes each placeholder with corresponding argument, applying formatting rules for numbers, strings, dates, etc. If the number of arguments does not match the placeholders, the function may raise an error or ignore extras, depending on implementation. Some variants escape special percent signs with %% to print a literal percent character.

Return values and side effects: some versions return the number of characters written or the resulting string; others raise exceptions on error. Many implementations align with the surrounding language's conventions for I/O and error handling.

Usage notes: fmtPrint is typically used when formatted output is required without adding a newline automatically, or when the resulting string needs to be stored or further processed rather than sent directly to a terminal.

Relation to other functions: fmtPrint is often contrasted with fmtPrintln and fmtPrintf, which append a newline or use a different return type. Because fmtPrint is not a standard across languages, readers should consult the documentation of the specific library for exact syntax and behavior.
