Function Documentation

rdm_dbSetErrorHandler()

RDM_RETCODE rdm_dbSetErrorHandler ( RDM_DB db,
RDM_ERROR_FCN errorFunction,
void * userData
)

#include <rdmdbapi.h>

Replace default error reporting with a custom function.

This function accepts a pointer to a function that will be called when RDM detects an error. The provided function supersedes the internal errorFunction function. The error reporting function must be a void function with the correct prototype, as shown below.

In the function prototype

  • The RDM_RETCODE is the error code as defined in RDM header files
  • The character pointer points to the error message
  • The RDM_DB pointer will be the db where the error occurred
  • The void pointer is the same pointer which was passed to rdm_dbSetErrorHandler() function, allowing the error reporting function to retrieve more information if it is called.
void MyErr (
RDM_RETCODE errnum,
const char *errmsg,
void *userdata,
);
Locking Requirements
None
Return values
