FUNCTION loc_read_process_conf
DESCRIPTION
Parse the specified conf file and return info for the processes defined.
The format of the file should conform with izat.conf.
PARAMETERS:
conf_file_name: configuration file to read
process_count_ptr: pointer to store number of processes defined in the conf file.
process_info_table_ptr: pointer to store the process info table.
DEPENDENCIES
The file must be in izat.conf format.
RETURN VALUE
0: success
none-zero: failure
SIDE EFFECTS
N/A
NOTES:
On success, memory pointed by (*process_info_table_ptr) must be freed.
