Function Documentation

unsigned int CLI_command (  const char *    line, const char *    prompt, const CLI_Syntax *    syntax, void *    user )

Parse and dispatch command lines. Parameters: ilin  Input line to parse (can be NULL or blank) prompt  Command prompt to use (when in subcommand mode) syntax  (Opaque) pointer to syntax to use to decode lines user  (Opaque) pointer to user parameter(s) Returns: Status code CLI_command parses and dispatches command lines. It handles the direct command case (when ilin contains a real string) and the 'enter subcommand' case (when ilin is NULL or blank).

CLI_Control * CLI_createCtl (  const CLI_Syntax *    syntax )  [static]

Allocate and initialize a CLI control structure. Parameters: syntax  Syntax to use to parse lines Return values: NULL  Allocation/initialization failed x  Pointer to created control structure

char * CLI_getFile (  CLI_Control *    ctl )  [static]

Fetch a line of input from a file. Parameters: ctl  A CLI control structure Return values: NULL  End of input x  Pointer to input line

unsigned int CLI_getLine (  FILE *    fd, char **    flin, int *    nlin )  [static]

Construct the next logical line of input in a file. Parameters: fd  File desciptor flin  Line (returned) nlin  Number of physical lines in logical line (returned) Returns: Status code

char * CLI_getTerm (  const char *    prompt )  [static]

Fetch a line of input from the terminal. Parameters: prompt  Terminal prompt Return values: NULL  End of input x  Pointer to input line
