sdftyp Analyze data type and length of operands

The sdftyp function analyzes an operand at a given position to ascertain its data type and its length. The position corresponds to the position defined with the SDF-A statement ADD-OPERAND ..., RESULT-OPERAND-NAME=*POS(...).

Format 1:

---

int sdftyp (char *area, int pos, int *typ, int *lng);

---

Format 2:

---

int sdftypls (char *area, int pos, int *typ, int *lng, int lst);

---

Description of the parameters

char *area	Pointer to the buffer in which the standardized transfer area was created (see sdfinit).
int pos	Position of the operand (as specified in ADD-OPERAND ..., RESULT-OPERAND-NAME=*POS(...)).
int *typ	Pointer to a value containing the type of the operand (see "Format of the standardized transfer area").
int *lng int lst	Pointer to the length of the operand. Relevant only if the operand is an element in a list and specifies the position of the operand in the list.

Result

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