strncat

Append the specified number of characters from one string to another.

Syntax

strncat(string-expr1, string-expr2, expr)

Where:

string-expr1	specifies an nstring variable.
string-expr2	specifies an nstring variable or a string constant.
expr	specifies a number or an expression of type int4 that specifies the maximum number of characters to concatenate.

Discussion

The strncat command appends the specified number of characters (expr) from the second string (string-expr2) to the end of the first string (string-expr1). Copying of the second string continues until a null terminating character is copied or the specified number of character have been copied. The string-expr2 is left unchanged.

Example

Command input:

define nstring a = "10.86"
define nstring b = "22."
strncat(b, a, 2)
b

Result:

"22.10"
