This function returns the persistent identifier (PID) of the symbolic dictionary for the data store (DS) specified in the passed environment to the specified field.
Format
#include <c$to2.h> long TO2_getDSdictPID (TO2_PID_PTR pid_ptr, TO2_ENV_PTR env_ptr);
Normal Return
The normal return is a positive value and the specified TO2_PID_PTR field will contain the PID of the data store dictionary.
Error Return
An error return is indicated by a zero. When zero is returned, use the TO2_getErrorCode function to determine the specific error code. For more information, see Error Handling.
The following error codes are common for this function:
TO2_ERROR_ENV
TO2_ERROR_NOT_INIT
Programming Considerations
None.
Examples
The following example copies the PID of the data store dictionary for data store TEST1_DS.
#include <c$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_PID dictionaryPID; /* return area for PID */ long userTkn = 0; char ApplicationName[33]="ApplicationName1 "; char DSname[]="TEST1_DS"; /* data store name blank padded */ TO2_ERR_CODE to2_rc=1; /* return code receiver */ TO2_ERR_TEXT_PTR err_textPtr; /* TO2 error code text pointer */
