pcgetr(3NCARG)


NAME

   PCGETR - Retrieves the real value of an internal parameter of type REAL
   or INTEGER.

SYNOPSIS

   CALL PCGETR (PNAM,RVAL)

C-BINDING SYNOPSIS

   #include <ncarg/ncargC.h>

   void c_pcgetr (char *pnam, float *rval)

DESCRIPTION

   PNAM        (an input expression of type CHARACTER) specifies the name
               of the parameter to get. The name must appear as the first
               two characters of the string. If the internal parameter is
               one of the two (BC and CC) that are arrays, the index
               of the desired array element may appear, enclosed in
               parentheses, in columns 3 and following. Other characters
               may be used to document the use of the parameter being
               retrieved; for example, instead of just MA, one can use
               MA - MAPPING FLAG and, instead of CC(10), one can use
               CC(10) - SPECIAL COLOR 10.

   RVAL        (an output variable of type REAL) is the name of the
               variable into which the value of the internal parameter
               specified by PNAM is to be retrieved.  If the internal
               parameter is a value "r" of type REAL, the value returned
               is "r".  If the internal parameter is a value "i" of type
               INTEGER, the value returned is "REAL(i)".

C-BINDING DESCRIPTION

   The C-binding argument descriptions are the same as the FORTRAN
   argument descriptions.

USAGE

   This routine allows you to retrieve the current value of Plotchar
   parameters.  For a complete list of parameters available in this
   utility, see the plotchar_params man page.

EXAMPLES

   Use the ncargex command to see the following relevant examples: cpexcc,
   epltch, vvexcc, fpchiqu.

ACCESS

   To use PCGETR or c_pcgetr, load the NCAR Graphics libraries ncarg,
   ncarg_gks, and ncarg_c, preferably in that order.

MESSAGES

   See the plotchar man page for a description of all Plotchar error
   messages and/or informational messages.
