Detailed Description

Prototype for a function to parse color config.

Parameters

[in]	buf	Temporary Buffer space
[in]	s	Buffer containing string to be parsed
[out]	fg	Foreground colour (set to -1)
[out]	bg	Background colour (set to -1)
[out]	attrs	Attributes, e.g. A_UNDERLINE
[out]	err	Buffer for error messages

Return values

0	Success
-1	Error
