This function determines the data store (DS) name for a persistent identifier (PID).
Format
#include <c$to2.h> long TO2_getDSnameForPID(const TO2_PID_PTR pid_ptr, TO2_ENV_PTR env_ptr, char dsname[TO2_MAX_DSNAME] );
Normal Return
The normal return is a positive value.
Error Return
An error return is indicated by a zero. When zero is returned, use the TO2_getErrorCode function to determine the specific error code. For more information, see Error Handling.
Programming Considerations
None.
Examples
The following example retrieves the DS name for the PID indicated.
#include <c$to2.h> /* Needed for TO2 API functions */ #include <stdio.h> /* APIs for standard I/O functions */ long err_code; TO2_ENV_PTR env_ptr; /* Pointer to TO2 environment */ TO2_PID collect; char dsname[8];
