Enumeration Type Documentation

enum ggept_status

Extraction interface return types. Enumeration values: GGEP_OK  OK, extracted what was asked. GGEP_NOT_FOUND  OK, but did not find it. GGEP_INVALID  Error, found something invalid. GGEP_BAD_SIZE  Error, buffer not correctly sized.

Function Documentation

ggept_status_t ggept_alt_extract (  extvec_t *  exv, struct gnutella_host **  hvec, gint *  hvcnt )

Extract vector of IP:port alternate locations. Parameters: `exv'  no brief description. `hvec'  pointer is filled with a dynamically allocated vector. `hvcnt'  is filled with the size of the allocated vector (number of items). Unless GGEP_OK is returned, no memory allocation takes place.

gint ggept_du_encode (  guint32  uptime, gchar *  data )

Encode `uptime' for the GGEP "DU" extension into `data'. Returns: the amount of chars written.

ggept_status_t ggept_du_extract (  extvec_t *  exv, guint32 *  uptime )

Extract daily uptime into `uptime', from the GGEP "DU" extensions.

ggept_status_t ggept_gtkg_ipv6_extract (  extvec_t *  exv, host_addr_t *  addr )

Extract IPv6 address into `addr' from GGEP "GTKG.IPV6" extension. A zero length indicates IPv6 support, a length of 16 or more indicates that the first 16 bytes are a IPv6 address.

ggept_status_t ggept_gtkgv1_extract (  extvec_t *  exv, struct ggep_gtkgv1 *  info )

Extract payload information from "GTKGV1" into `info'.

ggept_status_t ggept_h_sha1_extract (  extvec_t *  exv, gchar *  buf, gint  len )

Extract the SHA1 hash of the "H" extension into the supplied buffer. Returns: extraction status: only when GGEP_OK is returned will we have the SHA1 in buf. < XXX temporary, until we implement tiger

ggept_status_t ggept_hname_extract (  extvec_t *  exv, gchar *  buf, gint  len )

Extract hostname of the "HNAME" extension into the supplied buffer. Returns: extraction status: only when GGEP_OK is returned will we have extracted something in the supplied buffer.

gint ggept_lf_encode (  guint64  filesize, gchar *  data )

Encode `filesize' for the GGEP "LF" extension into `data'. Returns: the amount of chars written.

ggept_status_t ggept_lf_extract (  extvec_t *  exv, guint64 *  fs )

Extract filesize length into `filesize' from GGEP "LF" extension.

ggept_status_t ggept_push_extract (  extvec_t *  exv, struct gnutella_host **  hvec, gint *  hvcnt )

Extract vector of IP:port push proxy locations. The `hvec' pointer is filled with a dynamically allocated vector, and the `hvcnt' is filled with the size of the allocated vector (number of items). Unless GGEP_OK is returned, no memory allocation takes place.
