## Detailed Description

Teamd daemon control library

## Header

#include <teamdctl.h>

## Function Documentation

## ◆ teamdctl_alloc()

TEAMDCTL_EXPORT struct teamdctl * teamdctl_alloc | ( | void |  | ) |

Allocates library context and does initial setup.

Returns
  New libteam library context.

## ◆ teamdctl_config_actual_get_raw()

TEAMDCTL_EXPORT char * teamdctl_config_actual_get_raw | ( | struct teamdctl * | tdc | ) |

Parameters

  tdc | libteamdctl library context

Gets raw actual config string. Using reply cache. Return value is never NULL. To refresh the cache, use teamdctl_refresh function. Note: the obtained string should not be modified or freed by caller.

Returns
  Pointer to cached actual config string.

## ◆ teamdctl_config_actual_get_raw_direct()

TEAMDCTL_EXPORT int teamdctl_config_actual_get_raw_direct | ( | struct teamdctl * | tdc,
|  | char ** | p_cfg )

Parameters

  tdc | libteamdctl library context
  p_cfg | pointer to string which will be set

Gets raw actual config string. Does direct method call avoiding possible stale data in the cache. Note: the obtained string should not be modified or freed by caller.

Returns
  Zero on success or negative number in case of an error.

## ◆ teamdctl_config_get_raw()

TEAMDCTL_EXPORT char * teamdctl_config_get_raw | ( | struct teamdctl * | tdc | ) |

Parameters

  tdc | libteamdctl library context

Gets raw config string. Using reply cache. Return value is never NULL. To refresh the cache, use teamdctl_refresh function. Note: the obtained string should not be modified or freed by caller.

Return Pointer to cached config string.

## ◆ teamdctl_config_get_raw_direct()

TEAMDCTL_EXPORT int teamdctl_config_get_raw_direct | ( | struct teamdctl * | tdc,
|  | char ** | p_cfg )

Parameters

  tdc | libteamdctl library context
  p_cfg | pointer to string which will be set

Gets raw config string. Does direct method call avoiding possible stale data in the cache. Note: the obtained string should not be modified or freed by caller.

Parameters

  tdc | libteamdctl library context
  team_name | team device name
  addr | address (for zeromq only)

Returns
  Zero on success or negative number in case of an error.
