SYNOPSIS
       #include <encap.h>

       typedef int (*verfunc_t)(void *, char *, char *);
       int encap_find_versions(char *source, char *pkgname, verfunc_t verfunc,
       void *state);

VERSION

DESCRIPTION
       The encap_find_versions() function scans the Encap Source directory
       source for all versions of package pkgname.  For each version which is
       found, the function pointed to by verfunc is called.  If verfunc
       returns -1, encap_find_versions() returns immediately.

RETURN VALUES
       On success, the encap_find_versions() function returns the number of
       versions found.  If verfunc returns -1, encap_find_versions() returns
       -2.  On other errors, encap_find_versions() returns -1 and sets the
       global variable errno.
