atoi

Converts a string to an integer value.

int atoi( const char *string);

atoi reads the initial portion of the string only, by stopping at the first non-numerical character.

Return Values

The converted integer value of the input string. On overflow the result is undefined. If an error occurs, returns 0.

Example

The following example converts the initial portion of the string, s, to an integer.

    int i; 
    char * s = "7 dollars";
    i = atoi(s);
    lr_output_message ("Price $%d", i);

Example: Output:
vuser_init.c(7): Price $7
