[1mdpm_get [22mmakes a set of existing files available for I/O.

The input arguments are:

specifies the number of files belonging to the request.

specifies the array of file requests (dpm_getfilereq struc-

struct dpm_getfilereq {
char *from_surl;
time_t lifetime;
char f_type;
char s_token[CA_MAXDPMTOKENLEN+1];
char ret_policy;
int flags;

specifies the number of protocols.

specifies the array of protocols.

specifies the user provided description associated with the

This field is currently ignored.

The output arguments are:

Address of a buffer to receive the system allocated token. The
buffer must be at least CA_MAXDPMTOKENLEN+1 characters long.

will be set to the number of replies in the array of file sta-

will be set to the address of an array of dpm_getfilestatus
structures allocated by the API. The client application is
responsible for freeing the array when not needed anymore.

struct dpm_getfilestatus {
char *from_surl;
char *turl;
u_signed64 filesize;
int status;
char *errstring;
time_t pintime;

This routine returns 0 if the operation was successful or -1 if the
operation failed. In the latter case, [1mserrno [22mis set appropriately.

[1mEFAULT [4m[22mreqfiles[24m, [4mprotocols[24m, [4mr_token[24m, [4mnbreplies[24m or [4mfilestatuses[24m is
a NULL pointer.

[1mENOMEM [22mMemory could not be allocated for marshalling the request.

[1mEINVAL [4m[22mnbreqfiles[24m or [4mnbprotocols[24m is not strictly positive, the
protocols are not supported, the length of the user
request description is greater than 255 or all file
requests have errors.

[1mSENOSHOST [22mHost unknown.

[1mSEINTERNAL [22mDatabase error.
