Detailed Description
Channel protocol parser and commands.
This file contains the channel protocol parser and the definition of the protocol commands. Commands are defined in a "CmdTemplate" type array, containing:
- the name of the command,
- the arguments it expects to receive,
- the output values,
- the name of the function implementing the command.
The arguments and results are passed to command function using an union: the element of the union to use for each argument is determined by format strings present in the CmdTemplate table.
Definition in file parser.c.
Function Documentation
| static bool parseArgs | ( | const char * | fmt, |
| const char * | input, | ||
| parms | argv[] | ||
| ) | [static] |
Command arguments parser.
Using the format pointed by the argument fmt parses the input string filling the array argv with input parameters of the correct type.
- Parameters:
-
fmt Parameters format string. input Input string. argv Array filled with parameters.
- Returns:
- False in case of errors, otherwise true.
