The sdfinit function initializes the buffer in which the standardized transfer area is stored. The internal name of the program must be specified as it is defined in the syntax file.

The sdfinit function must be called once before all other SDF-C functions that use the standardized transfer area.

Format:

---

int sdfinit (char *area, int lng, STR8 progname);

Result

The function returns an integer as its result (see "Description of the C functions").
