* general token extraction
input: ppch pointer to pointer to command
szToekns - string of token separators
output: NULL if no token found
ptr to extracted token if found. Token is in original location
in input string, but null terminated if not quoted, token
will have been moved forward over quote character when quoted
ie:
input: ' abcd efgh'
output ' abcd\0efgh'
return value points to abcd, ppch points to efgh
input ' "jklm" nopq'
output ; jklm\0 nopq'
return value points to jklm, ppch points to space before
the 'n'
ppch points past null terminator
ignores leading whitespace, advances ppch over token and trailing
whitespace
matching single or double quotes are allowed, any character outside
of quotes or in doubly quoated strings can be escaped with a
backslash and will be taken as literal. Backslashes within single
quoted strings are taken literally. Multiple quoted strins can be
concatentated.
For example: input ' abc\"d"e f\"g h i"jk'l m n \" o p q'rst uvwzyz'
with the terminator list ' \t\r\n\v\f'
The returned token will be the string
<abc"de f"g h j ijkl m n \" o p qrst>
ppch will point to the 'u'
The \" between c and d is not in a single quoted string, so is reduced to
a double quote and is *not* the start of a quoted string.
The " before the 'd' begins a double quoted string, so spaces and tabs are
not terminators. The \" between f and g is reduced to a double quote and
does not teminate the quoted string. which ends with the double quote
between i and j. The \" between n and o is taken as a pair of literal
characters because they are within the single quoted string beginning
before l and ending after q.
It is not possible to put a single quote within a single quoted string.
You can have single quotes unescaped withing double quoted strings and
double quotes unescaped within single quoted strings.
