Freeing memory used by sqlda in ESQL/C

When using an sqlda structure in Informix ESQL/C, what is the proper way to free the memory after use? We are using a DESCRIBE statement, which causes Informix to create an sqlda struct with a pointer to an sqlvar_struct array. We allocate a buffer and assign sqldata to point to it; after use, we free the buffer. Does Informix free the rest of the data, such as the sqlind, sqlname, etc., or should we? Does Informix free the sqlvar_struct array? The sqlda? What is the right way to prevent a memory leak? -- Vic Schoenberg vic@csn.org
