# lrd_env_init

Allocates and initializes an LRDDBI handle. (Oracle 8.0 and later)

    LRDRET lrd_env_init( unsigned int muiDBType, void **mppvLRDDBIHandleEnv, unsigned long muliMode, int miDBErrorSeverity);

muiDBType | The target Database Types.
mppvLRDDBIHandleEnv | A pointer to a pointer to an LRDDBI handle.
muliMode | The operation mode.
miDBErrorSeverity | The Error Severity Levels of a failure in a database routine.

The lrd_env_init function allocates and initializes an LRDBI environment handle. If the pointed-to pointer is NULL, a new LRDDBI environment handle is allocated. If the value is non-NULL, if the pointed-to LRDDBI handle has the requested attribute, no new LRDDBI handle is allocated, and the function returns successfully. Otherwise, the LRDRET_E_EXISTING_HANDLE_ERROR is returned.

This function is only supported for Oracle 8.0 and higher.

For more details refer to the Function Header File lrd.h in the include directory.
