krb5_ccache_intro \- The credential cache functions 

.SH "Kerberos credential caches"
.PP
krb5_ccache structure holds a Kerberos credential cache\&.
.PP
Heimdal support the follow types of credential caches:
.PP
.IP "\(bu" 2
SCC Store the credential in a database
.IP "\(bu" 2
FILE Store the credential in memory
.IP "\(bu" 2
MEMORY Store the credential in memory
.IP "\(bu" 2
API A credential cache server based solution for Mac OS X
.IP "\(bu" 2
KCM A credential cache server based solution for all platforms
.PP
.SS "Example"
This is a minimalistic version of klist: 
.PP
.nf
#include <krb5\&.h>

int
main (int argc, char **argv)

    krb5_context context;
    krb5_cc_cursor cursor;

        errx(1, "krb5_context");

    ret = krb5_cc_default (context, &id);
    if (ret)

    while((ret = krb5_cc_next_cred(context, id, &cursor, &creds)) == 0){
        char *principal;

        krb5_unparse_name(context, creds\&.server, &principal);
        printf("principal: %s\\n", principal);
