.TH KVA_MATCH 3SECDB "Aug 12, 1999"
.SH NAME
kva_match \- look up a key in a key-value array
.SH SYNOPSIS
.LP
.nf
cc [ \fIflag\fR... ] \fIfile\fR...- lsecdb [ \fIlibrary\fR... ]
#include <secdb.h>

\fBchar *\fR\fBkva_match\fR(\fBkva_t *\fR\fIkva\fR, \fBchar *\fR\fIkey\fR);
.fi

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

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