View Ref-File[ Function Calling ]

Syntax:
               <name> ( <arg> [, ...] )
               <name> ()

where <name> is the function name and the value of <arg> is passed to
the corresponding function parameter.

Function arguments can be variables, constants or expressions.
Functions can be used as part of an expression, or simply as a
statement by itself (the return value does not have to be used).

Examples:

  fd = fopen("file.dat", "w");   /* FILE *fd */

  strcpy(array, "string");   /* char array[32] */

  if( fwrite(array, strlen(array), 1, fd) ) return(-1);
