Checks if the first character after any whitespace in a piece of JSON text is an opening brace.
JSONGETOBJECTSTART(p,l)
JSONGETOBJECTSTART reads up to and including the first non-whitespace character in the JSON text buffer to see if there is the opening brace ({) character. If there is, JSONGETOBJECTSTART returns the position of this character; otherwise a zero is returned indicating that it is not found.
Assuming buffer (pointed to by p) contains 2 blanks followed by {"Last": "Presley"}, Bytes = jsongetobjectstart(p,l); will return 3 (position of {).
None.
