Pl_Exp_Listerr_Script(101) - Roper Photometric Owner's Manual

PVCAM Class 101: ICL
NAME pl_exp_listerr_script – if an error occurred during script processing, list
boolean
SYNOPSIS
By default, this function returns zeros for all values, indicating that no logical or
DESCRIPTION
syntactical error was spotted in the script. This function resets each time
pl_exp_setup_script is called. If the last call to pl_exp_setup_script
generates an error, this function returns the location (where processing stopped)
of that error in the script string. In some cases, the location reported may just be
past the location of the actual error.
The character that generated the error is returned in err_char . This will be
character number err_char_num in the input string (0-indexed, as with all C
strings). The script is also examined for line-feed, newlines, etc. in an attempt to
divide the script into the separate lines used by common word processors. The
line number and character in the line are returned in err_line and
err_ch_in_line . Both of those values are 1-indexed, as is typical with text
editors and word processors, so that the first character in the script is character 1
of line 1.
TRUE for success, FALSE for a failure. Failure sets pl_error_code.
RETURN VALUE
pl_exp_setup_script(101)
SEE ALSO
Separate error lists are kept for each hcam , so multiple cameras (and multiple
NOTES
users) will not collide. This reports on the error state following the most recent
call to pl_exp_setup_script( ) using this value of hcam . A new call to
pl_exp_setup_script( ) resets the error list.
Some errors indicate a problem with the entire program rather than a single line
(for example, errors 10122 or 10123). In such a case, the error will be listed as
occurring at "character 0, line 0." This indicates that while no single line is at
fault, there was an inconsistency in the program at large.
pl_exp_listerr_script( int16 hcam, char_ptr err_char,
uns32_ptr err_char_num, uns32_ptr err_line,
uns32_ptr err_ch_in_line )
the exact position of that error.
