## Detailed Description

## Typedef Documentation

## ◆ opj_procedure

typedef void(* opj_procedure) (void)

declare a function pointer

## ◆ opj_procedure_list_t

typedef struct opj_procedure_list opj_procedure_list_t

A list of procedures.

## Function Documentation

## ◆ opj_procedure_list_add_procedure()

OPJ_BOOL opj_procedure_list_add_procedure | ( | opj_procedure_list_t * | p_validation_list,
|  | opj_procedure | p_procedure,
|  | opj_event_mgr_t * | p_manager
| ) |  |

Adds a new validation procedure.

Parameters

  p_validation_list | the list of procedure to modify.
  p_procedure | the procedure to add.
  p_manager | the user event manager.

Returns
  OPJ_TRUE if the procedure could be added.

## ◆ opj_procedure_list_clear()

void opj_procedure_list_clear | ( | opj_procedure_list_t * | p_validation_list | ) |

Clears the list of validation procedures.

Parameters

  p_validation_list | the list of procedure to clear.

## ◆ opj_procedure_list_create()

opj_procedure_list_t* opj_procedure_list_create | ( | void |  | ) |

Creates a validation list.

Returns
  the newly created validation list.

## ◆ opj_procedure_list_destroy()

void opj_procedure_list_destroy | ( | opj_procedure_list_t * | p_list | ) |

Destroys a validation list.

Parameters

  p_list | the list to destroy.

## ◆ opj_procedure_list_get_first_procedure()

opj_procedure* opj_procedure_list_get_first_procedure | ( | opj_procedure_list_t * | p_validation_list | ) |

Gets the pointer on the first validation procedure.

This function is similar to the C++ iterator class to iterate through all the procedures inside the validation list. the caller does not take ownership of the pointer.

Parameters

  p_validation_list | the list of procedure to get the first procedure from.

Returns
  a pointer to the first procedure.

## ◆ opj_procedure_list_get_nb_procedures()

OPJ_UINT32 opj_procedure_list_get_nb_procedures | ( | opj_procedure_list_t * | p_validation_list | ) |

Gets the number of validation procedures.

Parameters

  p_validation_list | the list of procedure to modify.

Returns
  the number of validation procedures.
