RTAPI_SNPRINTF(3)

NAME
rtapi_snprintf, rtapi_vsnprintf - Perform snprintf-like string formatting

SYNTAX

    int rtapi_snprintf(char* _buf_, unsigned long int _size_, const char* _fmt_, _..._);
    int rtapi_vsnprintf(char* _buf_, unsigned long int _size_, const char* _fmt_, va_list _apf);

ARGUMENTS

As for snprintf(3) or vsnprintf(3).

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.

REALTIME CONSIDERATIONS

May be called from non-realtime, init/cleanup, and realtime code.

RETURN VALUE

The number of characters written to buf.
