NAME

       dpm_accessr - check existence/accessibility of a file replica in the pools

SYNOPSIS

       #include <sys/types.h>
       #include <unistd.h>
       #include "dpm_api.h"

       int dpm_accessr (const char *pfn, int amode);

DESCRIPTION

       dpm_accessr checks the existence or the accessibility of the file replica according to the
       dpm. The name server entry for  the  replica  is  taken  into  account  and  that  of  the
       associated pool and, if relevant, the status of an ongoing put request.  The physical file
       name pfn is checked according to the bit pattern in amode

RETURN VALUE

       This routine returns 0 if the operation was successful or -1 if the operation  failed.  In
       the latter case, serrno is set appropriately.

ERRORS

                    replica status is not 'P' (cannot modify an existing file).

       EFAULT       pfn is a NULL pointer.

       EINVAL       amode is invalid.

       ENAMETOOLONG The length of pfn exceeds CA_MAXSFNLEN.
