p Up to .Fa buflen characters will be placed in .Fa buf , including the null terminator. If .Fa buf is not large enough to hold the entire string, then an error will be returned.

p The .Fa members argument controls which members of the set are written out. If .Fa members is .Sy 1 , then the sets member are placed in .Fa buf . If .Fa members is .Sy 0 , then the members which are not in the set are placed in .Fa buf .

p The string .Fa delim will be placed in-between every member of the set. It will not come after the last entry in the set. .Sh RETURN VALUES Upon successful completion, the .Fn proc_fltset2str , .Fn proc_sigset2str , and .Fn proc_sysset2str functions return .Fa buf . Otherwise, .Dv NULL is returned. .Sh INTERFACE STABILITY .Sy Uncommitted .Sh MT-LEVEL .Sy MT-Safe .Sh SEE ALSO .Xr libproc 3LIB , .Xr proc_fltname 3PROC , .Xr proc_signame 3PROC , .Xr proc_str2flt 3PROC , .Xr proc_str2fltset 3PROC , .Xr proc_str2sig 3PROC , .Xr proc_str2sigset 3PROC , .Xr proc_str2sys 3PROC , .Xr proc_str2sysset 3PROC , .Xr proc_sysname 3PROC , .Xr proc 4
