SYNOPSIS mixed get_type_info(mixed arg) mixed get_type_info(mixed arg, int flag) DESCRIPTION Returns info about the type of arg, as controlled by the flag. If the optional argument is not given, an array is returned whose first element is an integer denoting the data type, as defined in . The second entry can contain additional information about arg. If flag is the number 0, only the first element of that array (i.e. the data type) is returned (as int). If is 1, the second element is returned. If is a closure, the setting 2 lets the efun return the object of the closure (which for 'lfun closures' is the object the lfun is defined in, which is not necessarily the object the closure is bound to). If is a struct, the setting 2 lets the efun return the base name of the struct. If is a lfun or context closure, the setting 3 lets the efun return the name of the program the closure was defined in. For other closures, setting 3 returns 0. If is a lfun or context closure, the setting 4 lets the efun return the name of the function. For other closures, setting 4 returns 0. For every other setting, -1 is returned. The secondary information is: - for mappings the width, ie the number of data items per key. - for symbols and quoted arrays the number of quotes. - for closures, the (internal) closure type, as defined in . - for strings 0 for shared strings, and non-0 for others. - for structs the unique identifier string - -1 for all other datatypes. BUGS This function seems to be due to frequent changes as the driver develops resp. is debugged. HISTORY Introduced in 3.2@127 Flag setting 2 was introduced in 3.2.1@84. Secondary string information was introduced in 3.2.7. Up to 3.2.7 inclusive, get_type_info(closure,2) did not return the object from a lambda closure or bound-lambda closure. In the 3.2 branch, the 'flag' argument could be of any type. LDMud 3.3.276 added the secondary information for structs. LDMud 3.3.548 added flag setting '3' for lfun/context closures. LDMud 3.3.708 added flag setting '4' for lfun/context closures. SEE ALSO debug_info(E), typeof(E), to_object(E)
