Informix DataBlade API Programmer's Manual DataBlade API Function Descriptions

The ifx_int8cvasc() function converts a value held as printable characters in a C char type into an int8 type number.

mint ifx_int8cvasc(strng_val, len,  int8_val)

	char *strng_val

	mint len;

	ifx_int8_t *int8_val;

 



strng_val  

is a pointer to a string.


len

is the length of the strng_val string.


int8_val

is a pointer to the int8 structure where ifx_int8cvasc() places the result of the conversion.

The character string, strng_val, can contain the following symbols:

• A leading sign, either a plus (+) or minus (-).
• An exponent that is preceded by either e or E. You can precede the exponent by a sign, either a plus (+) or minus (-).

The strng_val character string should not contain a decimal separator or digits to the right of the decimal separator. The ifx_int8svasc() function truncates the decimal separator and any digits to the right of the decimal separator. The ifx_int8cvasc() function ignores leading spaces in the character string.

When you use a nondefault locale (one other than U.S. English), ifx_int8cvasc() supports non-ASCII characters in the strng_val character string. For more information, see the Informix Guide to GLS Functionality.
