PLDLLIMPEXP void plabort ( PLCHAR_VECTOR  errormsg)

Much the same as plwarn(), but appends ", aborting operation" to the error message. Helps to keep source code uncluttered and provides a convention for error aborts.

If cleanup needs to be done in the main program, the user should write his/her own exit handler and pass it in via plsabort().

Parameters
errormsgThe error message.

PLDLLIMPEXP void plexit ( PLCHAR_VECTOR  errormsg)

In case of an abort this routine is called. It just prints out an error message and tries to clean up as much as possible. It's best to turn off pause and then restore previous setting before returning.

If cleanup needs to be done in the main program, the user should write his/her own exit handler and pass it in via plsexit(). This function should should either call plend() before exiting, or simply return.

Parameters
errormsgThe error message.

PLINT *  level,
PLFLT *  old_scale,

PLFLT *  old_offset,

)

Calculate scale of font size and scale of magnitude of vertical offset associated with superscripts and subscripts. Notes on arguments: ifupper must be either TRUE or FALSE on every call to plP_script_scale. The contents of the location pointed to by the level pointer must be zero on the first call to plP_script_scale, but not modified externally from then on. The contents of the locations pointed to by all other pointer arguments are initialized internally, and should not be modified externally.

Parameters
ifupperValue which is TRUE if superscripting, i.e., if incrementing the previous level, and FALSE if subscripting, i.e., decrementing the previous level.
levelPointer to a location which contains the value of the superscript/subscript level. That value is 0, +-1, +-2, etc., for no superscript/subscript, the first level of superscript/subscript, the second level of superscript/subscript, etc. Before the call the value is the old level, and after the call the value will be incremented (ifupper TRUE) or decremented (ifupper FALSE) from the previous value.
old_scaleA pointer to a location that contains after the call the old font size scale value.
scaleA pointer to a location that contains after the call the font size scale value. This value is 0.75^{|level|} where |level| is the magnitude of the value of the superscript/subscript level after the call.
old_offsetA pointer to a location that contains after the call the old value of the magnitude of the superscript/subscript offset.
offsetA pointer to a location that contains after the call the value of the magnitude of the superscript/subscript offset which is zero for |level|=0 and sum_{i=1}^{i=|level|} 0.75^{i-1}, otherwise.
