This function locates the entry represented by the specified key and removes the entry from the dictionary. The passed key is assumed to be 64 bytes in length.
Format
#include <c$to2.h> long TO2_removeTPFKey ( TO2_ENV_PTR env_ptr, const void *key);
Normal Return
The normal return is a positive value. The dictionary entry represented by the specified key is deleted.
Error Return
An error return is indicated by a zero. When zero is returned, use the TO2_getErrorCode function to determine the specific error code. For more information, see Error Handling.
The following error codes are common for this function:
TO2_ERROR_ENV
TO2_ERROR_LOCATOR_NOT_FOUND
Programming Considerations
A commit scope will be created for the TO2_removeTPFKey request. If the request is successful, the scope will be committed. If an error occurs while processing the TO2_removeTPFKey request, the scope will be rolled back.
Examples
The following example removes an element from the TPF system dictionary.
#include <c$to2.h> /* Needed for TO2 API Functions */ #include <stdio.h> /* APIs for standard I/O functions */ TO2_ENV_PTR env_ptr; /* Pointer to TO2 Environment */ TO2_ERR_CODE err_code; /* TO2 error code value */ TO2_ERR_TEXT_PTR err_text_ptr; /* TO2 error code text pointer */ u_char key[64] = "TPF.Key.is.64.characters.long ";
