Informix DataBlade API Programmer's Manual DataBlade API Function Descriptions

The rstoi() function converts a null-terminated string into a short integer value.

mint rstoi(string,  ival)

	char  *string;

	mint  *ival;

 



string  

is a pointer to a null-terminated string. 


ival

is a pointer to an mint value that holds the converted value. 

The legal range of values is from -32767 to 32767. The value -32768 is not valid because this value is a reserved value that indicates null.

If string corresponds to a null integer, ival points to the representation for a SMALLINT null. To convert a string that corresponds to a long integer, use rstol(). Failure to do so can result in corrupt data representation.
