NAME

osdVSPrintf - print formatted output of a variable argument list

ARGUMENTS

*fmt*	format of the output string as per sprintf(3S)
*args*	arguments to print

SYNOPSIS

osdVSPrintf() formats the arguments args according the format specified by fmt, using the same specifiers as sprintf(3S). osdVSPrintf() allocates a string large enough to hold the formatted output, which must be deallocated by the caller, and populates it with the arguments.

RETURN

Returns a string containing the formatted output. It is the responsibility of the caller to deallocate the memory for this string.

EXAMPLE


void myfprintf(char *fmt, va_list args)
{
	char *s;
	s = osdVSPrintf(fmt, args);
	fprintf(stderr, "ERROR: %s\\n", s);
	osdFree(s);
}

DIAGNOSTICS

Providing a null address as an argument to the string specifiers (e.g., "%s" ) will most likely result in a core dump.
