  [in] | data | Encoded cause bytes.
  [in] | len | Length of data in bytes.

Returns
  0 on success, negative on error.

## osmo_lcs_cause_enc()

int osmo_lcs_cause_enc | ( | struct msgb * | msg,
|  | const struct lcs_cause_ie * | lcs_cause
| ) |  |

Encode the value part of 3GPP TS 49.031 10.13 LCS Cause, without IEI and len.

Identically used in 3GPP TS 48.008 3.2.2.66. Usage example:

uint8_t *l = msgb_tl_put(msg, BSSMAP_LE_IEI_LCS_CAUSE); int rc = osmo_lcs_cause_enc(msg, &lcs_cause); if (rc < 0) goto error; *l = rc;

Parameters

  [in,out] | msg | Message buffer to append the LCS Cause values to.
  [in] | lcs_cause | LCS Cause values to enconde.

Returns
  length of bytes written to the msgb.
