[Csnd] Length limitation of sprintfk. Any workaround?

Subject	[Csnd] Length limitation of sprintfk. Any workaround?
	It appears to me that there is a string length limitation when using sprintfk. My instrument is assembling a scoreline argument using sprintfk, passing a file path as one of the p-fields: Sline sprintfk "i \"Instr_name\" 0 1 %d \"%s\" ", kID, Sfilepath printks("%s\n", 1, Sline) scoreline Sline, 1 For long file paths (due to a complex file structure) the Sline string ends up incomplete. I assume this is a limitation of sprintfk. Is there a workaround here? I can look into ways of shortening the paths, of course, but it would be nice with a more sustainable solution.

there should be no limit. Is the file path string right, I mean, can you isolate this to sprintkf?

If so, it's a bug and a ticket would be nice, with a short example demonstrating the issue.

thx
