char *sprintf(char *buf, const char *fmt, ... );
Solaris DDI specific (Solaris DDI).
sprintf() builds a string in buf under the control of the format fmt. The format is a character string with either plain characters, which are simply copied into buf, or conversion specifications, each of which converts zero or more arguments, again copied into buf. The results are unpredictable if there are insufficient arguments for the format; excess arguments are simply ignored. It is the user's responsibility to ensure that enough storage is available for buf.
Each conversion specification is introduced by the % character, after which the following appear in sequence:
An optional decimal digit specifying a minimum field width for numeric conversion. The converted value will be right-justified and padded with leading zeroes if it has fewer characters than the minimum.
An optional l (ll) specifying that a following d, D, o, O, x, X, or u conversion character applies to a long (long long) integer argument. An l (ll) before any other conversion character is ignored.
A character indicating the type of conversion to be applied:
A bit number is a binary-valued character in the range 1-32. For each bit set in the first argument, and named in the second argument, the bit names are copied, separated by commas, and bracketed by < and >. Thus, the following function call would generate reg=3<BitTwo,BitOne>\n in buf.
sprintf(buf, "reg=%b\n", 3, "\10\2BitTwo\1BitOne")
sprintf() can be called from user or interrupt context.
