gets( ) fgets( )
Syntax:
Parameters:
Returns:
Function:
gets (string)
value = fgets (string, stream)
string is a pointer to an array of characters.
Stream is a stream identifier (a constant byte)
undefined
Reads characters (using getc()) into the string until a RETURN (value 13) is
encountered. The string is terminated with a 0. Note that INPUT.C has a more
versatile get_string function.
If fgets() is used then the specified stream is used where gets() defaults to
STDIN (the last USE RS232).
Availability:
Requires:
Examples:
All devices
#USE RS232
char string[30];
printf("Password: ");
gets(string);
if(strcmp(string, password))
printf("OK");
