SE_STRUCT(memdesc)
You can use this macro to retrieve the member from an seMemberDesc structure and pass it to any of the functions. You store a member in the structure using the seStoreMember function. Here is a short code example:
struct seMemberDesc mem;
seStoreMember(&(mem),SE_NUM(0));
sePutNumber(se,myObj,SE_STRUCT(&mem), 10);
Member description structures are useful to pass a member identifier as a parameter to a function.
