Modifies a single field in the default parameter database.

DWORD adiConfigParm( char *parmname,
void *data,
unsigned size )

parmname Named specification of the parameter in the form "structure.field".

data Pointer to the new default value.

size Size of the parameter field value (the size must match the size of the parameter you are modifying).

• SUCCESS
• CTAERR_BAD_ARGUMENT
  parmname or data is NULL.
• CTAERR_BAD_SIZE
  size is zero, or the specified size does not match the parameter size.
• CTAERR_NOT_FOUND
  parmname does not exist.

None.

adiConfigParm changes the value of an AG Access parameter. This will affect all ports and contexts in the executing process.

The default values for AG Access parameters are used when a function call passes a NULL. You can retrieve the default values with adiGetParms or adiGetParmByName.

Note: When the AG Access daemon (addaemon) is running, default values for AG Access parameters are retained in system shared memory. Any process executing adiConfigParm will affect the default value seen by all running and future processes executed after the daemon was launched.
