This function returns the maximum number of entries for the log or keyed log.
Format
#include <c$to2.h> long TO2_maxEntry (const TO2_PID_PTR pid_ptr, TO2_ENV_PTR env_ptr);
Normal Return
The maximum number of entries for the log or keyed log will be returned as the return value.
Error Return
An error return is indicated by a zero. When zero is returned, use the TO2_getErrorCode function to determine the specific error code. For more information, see Error Handling.
The following error codes are common for this function:
TO2_ERROR_ENV
TO2_ERROR_METHOD
TO2_ERROR_PID
TO2_ERROR_ZERO_PID
TO2_ERROR_NOT_INIT
Programming Considerations
This function does not use TPF transaction services on behalf of the caller.
Examples
The following example returns the maximum number of entries.
#include <c$to2.h> /* Needed for TO2 API functions */ #include <stdio.h> /* APIs for standard I/O functions */ TO2_ENV_PTR env_ptr; /* PTR to the TO2 environment */ TO2_PID collect; /* PTR to PID return field */
