SYNOPSYS
parse_output_and_get_value()
command the command to execue with popen.
word the word to look for (usually an option name)
result the buffer to store the next word (option value)
result_len self-explanatory
get_all_line flag, which is set if we want to get all the line after
the matched word.
command the command to execue with popen.
word the word to look for (usually an option name)
result the buffer to store the next word (option value)
input_buffer_len self-explanatory
flag this equals to GET_LINE if we want to get all the line after
the matched word and GET_VALUE otherwise.
DESCRIPTION
Parse output of the "command". Find the "word" and return the next one
if get_all_line is 0. Return the rest of the parsed string otherwise.
if flag is GET_VALUE. Return the rest of the parsed string otherwise.
RETURN
0 - ok
