/*****************************************************************************
* Johns Hopkins University
* Center For Astrophysical Sciences
* FUSE
*****************************************************************************
*
* Synopsis: cf_error_init(char *prgmid, char *vernum, FILE *errfile)
*
* Description: Writes a timestamp, the calling program name, and an
* error message to stdout for a cfitsio routine.
*
* Arguments: char *progid Name of the calling program
* char *vernum Version of the calling program
* (should be version control number)
* FILE *errfile Output file name (default is stderr)
*
* Returns: none
*
* History: 02/22/99 peb Some simple functions to make error
* reporting easier. Deficiencies in
* cfitsio make printing comprehensive
* messages difficult.
* 03/15/99 emm Added cf_if_memory_error.
* 04/30/99 peb Added cf_malloc and cf_calloc.
* 06/07/99 peb Added reporting of version number
* 09/01/99 emm Added fflush to see if it helps print
* out error messages on failure.
* 11/08/99 emm Added !!!!!!!! to error reporting to
* better delimit the error message and
* to make them more obvious.
* 04/23/01 1.10 wvd Make cf_malloc & cf_calloc print error
* message returned by malloc & calloc
* 03/07/03 1.2 peb Added cf_verbose and external variable
* verbose_level
* 03/13/03 1.3 peb Enabled cf_verbose, cf_if_warning, and
* cf_if_error to accept a variable
* number of parameters. Changed the
* output format to print month, day, time
* hostname, function name and message.
* 03/25/03 1.4 peb Changed output to print time, program,
* and version number for warning and
* error messages.
* Changed output to use verbose_level
* to modify output format:
* level==1 prints program, version, and
* message.
* level>=2 prints only message.
* 10/30/03 1.5 peb Replaced cftime function with strftime
* for UNIX compatibility.
* Removed unnecessary header files,
* malloc.h and unistd.h
* 04/07/04 1.6 bjg fflush stdout and error_file
*
