mi_get_varlen()
Gets the length of the data contained in the structure.
mi_get_vardata()
Gets a pointer to the data contained in the structure.
mi_get_vardata_align()
Gets a pointer to the data contained in the structure, adjusting for any initial padding required to align the data on a particular byte boundary. (See the following information about the align value.)
mi_new_var()
Creates a new variable-length structure for text data.
mi_var_copy()
Allocates and creates a copy of a variable-length structure for text data.
mi_var_free()
Deallocates a variable-length structure.
mi_set_varlen()
Sets the length of the data contained in the structure.
mi_set_vardata()
Sets the data in the structure.
mi_set_vardata_align()
Sets the data in the structure, adjusting by adding any initial padding required to align the data on a particular byte boundary.
Use the mi_get_vardata_align() and mi_set_vardata_align() functions with data types whose alignment is not 4 bytes, the default value. When you create such data types, set the align argument to the align value that is in the sysxtdtypes table. For example, the mi_double_precision data type is aligned on an 8-byte boundary. To access the data portion of an array of mi_double_precision, use mi_get_vardata_align() with an align value of 8. The database server returns binary results for variable-length data from the database server in variable-length format. A value is variable length if a call to mi_column_type_length() for that column returns -1.
