Typedef Documentation

unsigned int CID_dispatch
 

Typedef for a command line callback routine.

Parameters:
pcnt Remaining parameter (token) count
parm Remaining parameters (tokens)
This defines the signature of a command line callback routine. The main routine peels off the first word (token) and tries to match it against a list of verbs. If a match is found, control is dispatched to the corresponding routine which must have this signature.

Function Documentation

unsigned int abbrev (  const char *  left,
unsigned int  llen,
const char *  rite,
unsigned int  rlen,
unsigned int  min
)  [static]
 

Test a string for being a minimally long abbreviation of another.

Parameters:
left String to test
llen Length of string to test
rite String to test against
rlen Length of string to test against
min Minimum length of overlap
Return values:
0 Success
1 Failure

unsigned int check (  unsigned int  pcnt,
const char *  parm[]
)  [static]
 

Check the syntax of an interface definition file.

Parameters:
pcnt Number of argument strings remaining
parm Array of pointers to argument strings
check() reads in the interface file and checks its syntax. If the syntax is good, the command will exit silently. If the syntax is bad, a list of syntax errors is printed.

Return values:
0 Success
1 Failure

Here is the call graph for this function:

unsigned int compare (  unsigned int  pcnt,
const char *  parm[]
)  [static]
 

Compare an "old" and a "new" interface definition file.

Parameters:
pcnt Number of argument strings remaining
parm Array of pointers to argument strings
compare() tests an old and a new interface definition file for "compatibility". On an interface by interface basis, compare() reports (prints) an "opinion". If the new interface increments the major release number, the opinion is "major". If the new interface keeps the same major release number but extends the interface the opinion will be either "minor" or "patch" depending on how the interface has been extended. All other cases (e.g. major release number decreases, interface instance in old no longer present in new, global symbol content of an interface instance changed between old and new, ...) produce the opinion "error".

Return values:
0 Success
1 Failure

Here is the call graph for this function:

unsigned int find (  unsigned int  pcnt,
const char *  parm[]
)  [static]
 

Find a symbol in an interface definition file.

Parameters:
pcnt Number of argument strings remaining
parm Array of pointers to argument strings
find() searches the instances in an interface definition file to find the requested global symbol(s). If found, the symbol is printed along with the name of the interface in which it was found. If the symbol cannot be found, the symbol name is still printed, but attributed to interface <untraceable>.

Return values:
0 Success
1 Failure

Here is the call graph for this function:

unsigned int show (  unsigned int  pcnt,
const char *  parm[]
)  [static]
 

Show some feature of an interface definition file.

Parameters:
pcnt Number of argument strings remaining
parm Array of pointers to argument strings
show() is simply a branch routine. It peels off the next parameter to identify either "global" or "interface" and branches to the relevant routine.

Return values:
0 Success
1 Failure

Here is the call graph for this function:

unsigned int show_global (  unsigned int  pcnt,
const char *  parm[]
)  [static]
 

Show global symbols in an interface file.

Parameters:
pcnt Number of argument strings remaining
parm Array of pointers to argument strings
show_global() simply lists all the symbols in all the interfaces defined in an interface definition file.

Return values:
0 Success
1 Failure

Here is the call graph for this function:

unsigned int show_interface (  unsigned int  pcnt,
const char *  parm[]
)  [static]
 

Show the interface names in an interface definition file.

Parameters:
pcnt Number of argument strings remaining
parm Array of pointers to argument strings
show_interface() prints information about the interfaces defined in an interface definition file. There are several options (see the "CMX User Manual" for details). The major options control (1) whether the display is indented to show the interface instance hierarchy, (2) whether the "symbol strength" of an interface instance is printed and (3) whether the globals defined in an interface instance are printed.

Return values:
0 Success
1 Failure
