  18 .SH DESCRIPTION
  19 .LP
  20 The \fBkva_match()\fR function searches a \fBkva_t\fR structure, which is part
  21 of the  \fBauthattr_t\fR, \fBexecattr_t\fR, \fBprofattr_t\fR, or
  22 \fBuserattr_t\fR structures. The function takes two arguments: a pointer to a
  23 key value array, and a key.  If the key is in the array, the function returns a
  24 pointer to the first corresponding value that matches that key.  Otherwise, the
  25 function returns \fINULL\fR.
  26 .SH RETURN VALUES
  27 .LP
  28 Upon successful completion, the function returns a pointer to the value sought.
  29 Otherwise, it returns \fINULL\fR.

  49 .SH NOTES
  50 .LP
  51 The \fBkva_match()\fR function returns a pointer to data that already exists in
  52 the key-value array. It does not allocate its own memory for this pointer but
  53 obtains it from the key-value array that is passed as its first argument.
