Detailed Description

Add the snprintf and vsnprintf functions to fioLib.

CVS $Id: fioLibX.c,v 1.1 2003/08/27 18:45:03 apw Exp $

Author:

A.P.Waite - apw@slac.stanford.edu

The "standard" I/O routines snprintf and vsnprintf are mysteriously missing from the VxWorks distribution. They can however be built out of the tools VxWorks provides. These are the implementations.

Function Documentation

unsigned int fioFormatV_cb (  char *  buf, int  siz, int  prm )

Format a message into the output buffer. Parameters: buf  (in) Text source buffer provided by fioFormatV() siz  (in) The number of letters in the text source buffer prm  (in) Pass through parameter from snprintf Callback routine for the VxWorks fioFormatV routine. Used to mimic the operation of the snprintf routine.

int snprintf (  char *  buf, int  siz, const char *  fmt,   ... )

Implement the standard snprintf() routine with VxWorks tools. Parameters: buf  (in) Pointer to current location in output buffer siz  (in) Size remaining in output buffer fmt  (in) Formatting string VxWorks does not provide a snprintf() entry point, but a substitute can be constructed using VxWorks provided tools. This is it.

int vsnprintf (  char *  buf, int  siz, const char *  fmt, va_list  list )

Implement the standard vsnprintf() routine with VxWorks tools. Parameters: buf  (in) Pointer to current location in output buffer siz  (in) Size remaining in output buffer fmt  (in) Formatting string list  (in) Varaible argument list description VxWorks does not provide a vsnprintf() entry point, but a substitute can be constructed using VxWorks provided tools. This is it.
