Comments

pL_FILEMETADATAITEM is a pointer to an L_FILEMETADATAITEM structure. Where the function parameter type is pL_FILEMETADATAITEM, you can declare a L_FILEMETADATAITEM variable, update the structure's fields, and pass the variable's address in the parameter. Declaring a pL_FILEMETADATAITEM variable is necessary only if your program requires a pointer.
