## Function Documentation

void dmxArgAdd | ( | dmxArg | a,
|  | const char * | string
| ) |

| Add the string as the next argument in the dmxArg object.

int dmxArgC | ( | dmxArg | a | ) |

| Return the number of arguments in the dmxArg object.

dmxArg dmxArgCreate | ( | void |  | ) |

| Create an (externally opaque) dmxArg object.

void dmxArgFree | ( | dmxArg | a | ) |

| Free the specified dmxArg object.

dmxArg dmxArgParse | ( | const char * | string | ) |

| Parse a string into arguments delimited by commas. Return a new dmxArg object containing the arguments.

const char* dmxArgV | ( | dmxArg | a,
|  | int | item
| ) |

| Return the argument number item in the dmxArg object. Arguments are 0 based. NULL will be returned for values less than 0 or equal to or greater than the number of arguments in the object.
