Function Documentation

int GetArgument (  char *    inString, char *    inArg, char *    outVal, int    valSize )

Gets a specified argument from an argument string. This function tries to find the argument and, if possible, its value. One-letter arguments can be grouped together as in "-xzf" but in this case all these arguments cannot have a value. Otherwise, values can be assigned with "--argument value" or "-a value". Parameters: inString  The argument string to parse. inArg  The argument to get. Must be a proper NULL-terminated string, even if it is a single letter. outVal  The value of the argument. Memory must already be allocated. valSize  The size, in bytes, of the pre-allocated outVal. Returns: 1 if and only if the argument is in the string. Definition at line 62 of file Args.c.

void MakeArgumentString (  int    argc, char **    argv, char *    outArgs, int    argsSize )

Makes a string from main-style argc and argv. Parameters: argc  The number of arguments. argv  Array to a list of argument strings of size argc. outArgs  The generated string. Memory must already be allocated. argsSize  The size, in bytes, of the pre-allocated outArgs. Definition at line 36 of file Args.c.
