  26. \fIwcsspn\fR()
  27. function shall compute the length (in wide characters) of the
  28. maximum initial segment of the wide-character string pointed to by
  29. .IR ws1
  30. which consists entirely of wide-character codes from the wide-character
  31. string pointed to by
  32. .IR ws2 .
  33. .SH "RETURN VALUE"
  34. The
  35. \fIwcsspn\fR()
  36. function shall return the length of the initial substring of
  37. .IR ws1 ;
  38. no return value is reserved to indicate an error.
