Description:
The sscanf() function scans input from the character string in_string, under control of the argument format. Following the format string is the list of addresses of items to receive values.
Returns:
The number of input arguments for which values were successfully scanned and stored, or EOF when the scanning is terminated by reaching the end of the input string.
Examples:
#include <stdio.h>
#include <stdlib.h>
int main( void )
{
int day, year;
char weekday[20], month[20];
sscanf( "Thursday February 0025 1999",
"%s %s %d %d",
weekday, month, &day, &year );
printf( "%s %d, %d is a %s\n",
month, day, year, weekday );
return EXIT_SUCCESS;
}
produces the following:
February 25, 1999 is a Thursday
