.SH NAME
rtapi_snprintf, rtapi_vsnprintf \- Perform snprintf-like string formatting
.SH SYNTAX
.HP
int rtapi_snprintf(char *\fIbuf\fR, unsigned long int \fIsize\fR, const char *\fIfmt\fR, \fI...\fR)
.HP
int rtapi_vsnprintf(char *\fIbuf\fR, unsigned long int \fIsize\fR, const char *\fIfmt\fR, va_list \fIapfB)
.SH ARGUMENTS
As for \fIsnprintf(3)\fR or \fIvsnprintf(3)\fR.
.SH DESCRIPTION
These functions work like the standard C printf functions, except that a
reduced set of formatting operations are supported.
In particular: formatting of long long values is not supported. Formatting of
floating-point values is done as though with %A even when other formats like %f
are specified.

May be called from user, init/cleanup, and realtime code.
.SH RETURN VALUE
The number of characters written to \fIbuf\fR.
.SH SEE ALSO
\fBprintf(3)\fR
