Description

This function will search for the specified configuration file and then extract the information from the specified line. The file can be read only and is closed when done.

Note that cfp_file() is used to find the correct path of the desired file.

Return Value

The return value is a pointer to the found line or NULL if an error occurs.

Example

To find out the detector name:

"cfp_getln(name, CFHT_DETECTOR, CFHT_CONFNAME, NULL);"
