◆ plexit()

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

errormsg The error message.

		PLINT *	level,
		PLFLT *	old_scale,

	)

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

ifupper	Value which is TRUE if superscripting, i.e., if incrementing the previous level, and FALSE if subscripting, i.e., decrementing the previous level.
level	Pointer 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_scale	A pointer to a location that contains after the call the old font size scale value.
scale	A 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_offset	A pointer to a location that contains after the call the old value of the magnitude of the superscript/subscript offset.
offset	A 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.

◆ plParseDrvOpts()

PLDLLIMPEXP int plParseDrvOpts ( DrvOpt * acc_opt )

Parse driver specific options

Parameters

acc_opt ?

Returns: 0 if successful.

◆ plreadmetafile()

PLDLLIMPEXP void plreadmetafile ( char * infile )

Reads a PLplot metafile and uses the current plot stream to display the contents. If the plot stream has not been initialized, this routine will attempt to intialize the plot stream via a plinit() call. For an initialized plot stream, the metafile will start at the current page/subpage.

Parameters

infile Input PLplot metafile name.

Pass NULL for infile to use the filename passed from the command line option -mfi.

Returns void

◆ plrestore_locale()

PLDLLIMPEXP void plrestore_locale ( char * saved_lc_numeric_locale )

Restore LC_NUMERIC locale string that was determined by plsave_set_locale with the pointer to that string as the argument. Also, free the memory for that string.

Parameters

saved_lc_numeric_locale The saved numeric locale..

◆ plsave_set_locale()

PLDLLIMPEXP char* plsave_set_locale ( void )

Save LC_NUMERIC locale in a string. The pointer to that string is returned. Then set LC_NUMERIC to "C" locale. n.b. plsave_set_locale and plrestore_locale should always be used as a pair to surround PLplot code that absolutely requires the LC_NUMERIC "C" locale to be in effect. It is one of plrestore_locale's responsibilities to free the memory allocated here for the locale string.

Returns: The LC_NUMERIC locale.

◆ plsnprintf()

int plsnprintf	(	char *	buffer,
		int	n,
		PLCHAR_VECTOR	format,
			...
	)

Dummy function for snprintf(). This function just calls the unsafe function ignoring the string size. This function will rarely be needed if ever.

Parameters

buffer	String output buffer.
n	Size of buffer.
format	The format string.
...	The values that go in the format string (...)

Returns: The length of buffer that is actually used.

Definition at line 3013 of file plctrl.c.

◆ plsnscanf()

int plsnscanf	(	PLCHAR_VECTOR	buffer,
		int	n,
		PLCHAR_VECTOR	format,
			...
	)

Dummy function for snscanf(). This function just calls the unsafe function ignoring the string size. This function will rarely be needed if ever.

Parameters

buffer	String output buffer.
n	Size of buffer.
format	The format string.
...	The values that go in the format string (...)

Returns: The length of buffer that is actually used.
