◆ Vnm_exec()

int Vnm_exec	(	int	argc,
		char **	argv )

An improved UNIX "exec" call. This routine does not return except on error.

Author: Michael Holst

Note: Useful constants and functions (timers, epsilon, token generators, i/o)

Returns: no return except on error

Parameters

argc	number of the command line arguments
argv	the command line arguments

References Vnm_exec().

Referenced by Vnm_exec().

Here is the call graph for this function:

◆ Vnm_flush()

void Vnm_flush ( const int unit )

Attempt to flush the specified i/o stream. We MUST NOT use VASSERT (or Vnm_print!) in this routine.

Author: Michael Holst

Note: Useful constants and functions (timers, epsilon, token generators, i/o)

Returns: None

Parameters

unit	index for the file unit

References Vnm_flush().

Referenced by Vnm_flush().

Here is the call graph for this function:

◆ Vnm_gentokens()

int Vnm_gentokens	(	char *	buf,
		char **	argv,
		const int	argvmax,
		const char *	white,
		const char *	comment )

Generate an [argv,argc] pair from a character string "buf" (assumed NULL-terminated) in which tokens are separated by whitespace "white" with possible comments "comment" occuring. THE INPUT STRING IS MODIFIED HERE!

Author: Michael Holst

Note: Useful constants and functions (timers, epsilon, token generators, i/o)

Again, the input string "buf" IS MODIFIED; white space characters (defined in the input string "white") are replaced by the NULL character '\0'. The output "argv" is simply a list of pointers
to the start of the tokens in "buf", which are NULL-terminated
after we replace the white space with NULLs.

We follow convention and "NULL"-terminate "argv" by setting the pointer following the last token to "VNULL". The return value is "argc", the number of tokens found (not including the terminating NULL pointer). For safety you must pass in the maximal length of argv in the parameter "argvmax".

If we encounter a token which begins with a comment character (defined in the input string "comment"), then we ignore the rest of the tokens in the input buffer "buf". This is suitable
for parsing shell languages such as sh/ksh/bash which have comments that start with e.g. "#" and continue until a newline.

We DO NOT use the C library function strtok in this routine. (There are some bad implementations of strtok around apparently; the internal state variables maintained by strtok can get very
messed up if you use strtok in multiple places in a code.)

Returns: number of tokens

Parameters

buf	buffer containing message
argv	the command line arguments
argvmax	maximal number of the command line arguments
white	Pointer to the input string
comment	token which begins with a comment character

Referenced by Vnm_gentokens().

Here is the call graph for this function:

◆ Vnm_getcwd()

char * Vnm_getcwd	(	char *	path,
		int	pathmax )

Ask the system for the current working directory.

Author: Michael Holst

Note: Useful constants and functions (timers, epsilon, token generators, i/o)

Consider it an error if we can't return something useful; therefore we will VASSERT(path!=VNULL) before returning.

Note that unlike Vnm_gethome, a call to Vnm_getcwd returns the current directory, possibly modified from call to call.

I.e., calls to Vnm_chdir can change the current working
directory; Vnm_getcwd returns the current directory, whatever that might be.

Returns: the current working directory

Parameters

path	Pointer to the path
pathmax	index for the size of path

References Vnm_getcwd().

Referenced by Vnm_getcwd().

Here is the call graph for this function:

◆ Vnm_gethome()

char * Vnm_gethome	(	char *	path,
		int	pathmax )

Ask the system for the home directory.

=

Author: Michael Holst

Note: Useful constants and functions (timers, epsilon, token generators, i/o)

The following preference order is used to set the home directory:

MCSH_HOME (the user must define this in his environment)
CWD (always defined as the current working directory)

We consider it an error if we can't return something useful;
therefore we will VASSERT(path!=VNULL) before returning.

We settle on a home directory the first time we are called, and then we simply return this fixed home directory forever.
In other words, the first call to Vnm_gethome, regardless of
who makes the call, establishes the home directory for everyone else (as long as everyone goes through Vnm_gethome!).

Returns: the home directory

Parameters

path	Pointer to the path
pathmax	index for the size of path
