prordn() - Read DECIMAL Variable

The prordn() function reads the value of a shared DECIMAL numeric variable.

On successful completion, prordn() returns 0; otherwise, it returns a non-zero value:

Syntax

int prordn ( psymnam, index, pvar, punknown, varlen, pactlen ) char *psymnam; int index; char *pvar; int *punknown; int varlen; int *pactlen;

psymnam

This input parameter points to the name of the specified shared DECIMAL numeric variable. You supply the name from your OpenEdge application.

index

This input parameter specifies an index value for an array variable. If the variable is not an array, you must set the value of index to 0.

pvar

This output parameter points to a buffer where prordn() returns the value of the specified DECIMAL numeric variable, formatted as a character string.

punknown

This output parameter points to an integer where prordn() returns 1 if the variable has the Unknown value (?), and returns 0 otherwise.

varlen

This input parameter contains the length of the buffer that pvar specifies.

pactlen

This output parameter points to an integer where prordn() returns the actual length of the character string (in bytes) to which the DECIMAL numeric variable is converted.
