Detailed Description

Declarations for functions implementing libc stdarg functions.

Using EMBTEXTF_PROVIDE_LIBC embtextf can provide implementations for standard libc functions such as vprintf(), etc. based on an application-provided putchar() implementation.

These functions are provided: vprintf(), vsprintf(), vsnprintf()

These functions are required: putchar()

These functions are not provided: vfprintf()

Stream-oriented functions (viz. those that reference a libc FILE object) are not included as one might conceivably want to use FILE to hold the embtextf_putchar_fn instance that is used to perform output to that stream. If such an interface is desired it can be provided by the application.

Note

You must link libembtextf-libc.a along with libembtextf to incorporate the libc-related function wrappers into your application.
