#### Procedure

       SpiceInt isrchc_c ( ConstSpiceChar  * value,
                           SpiceInt          ndim,
                           SpiceInt          lenvals,
                           const void      * array   )

#### Abstract

       Search for a given value within a character string array. Return
       the index of the first matching array entry, or -1 if the key
       value was not found.

#### Required_Reading

       None.

#### Keywords

       ARRAY,  SEARCH

#### Brief_I/O

       VARIABLE  I/O              DESCRIPTION
       --------  ---  --------------------------------------------------
       value      I   Key value to be found in array.
       ndim       I   Dimension of array.
       lenvals    I   String length.
       array      I   Character string array to search.

       The function returns the index of the first matching array
       element or -1 if the value is not found.

#### Detailed_Input

       value       is the key value to be found in the array.  Trailing
                   blanks in this key are not significant:  string matches
                   found by this routine do not require trailing blanks in
                   value to match those in the corresponding element of
                   array.

       ndim        is the dimension of the array.

       lenvals     is the declared length of the strings in the input
                   string array, including null terminators.  The input
                   array should be declared with dimension

                      [ndim][lenvals]

       array       is the array of character srings to be searched.  Trailing
                   blanks in the strings in this array are not significant.

#### Detailed_Output

       The function returns the index of the first matching array
       element in array. If value is not found, isrchc_c returns -1.

#### Parameters

       None.

#### Exceptions

       1) If ndim < 1 the function value is -1.  This is not considered
          an error.

       2) If input key value pointer is null, the error SPICE(NULLPOINTER) will
          be signaled.  The function returns -1.

       3) The input key value may have length zero.  This case is not
          considered an error.

       4) If the input array pointer is null,  the error SPICE(NULLPOINTER) will
          be signaled.  The function returns -1.

       5) If the input array string's length is less than 2, the error
          SPICE(STRINGTOOSHORT) will be signaled.  The function returns -1.

       None.

#### Particulars

       None.

#### Examples

       The following table shows the value of isrchc_c given the contents
       of array and value:

          array                 value     isrchc_c
        -----------------       -----     --------
        "1", "0", "4", "2"       "4"          2
        "1", "0", "4", "2"       "2"          3
        "1", "0", "4", "2"       "3"         -1

#### Restrictions

       1)  String comparisons performed by this routine are Fortran-style:
           trailing blanks in the input array or key value are ignored.
           This gives consistent behavior with CSPICE code generated by
           the f2c translator, as well as with the Fortran SPICE Toolkit.

           Note that this behavior is not identical to that of the ANSI
           C library functions strcmp and strncmp.

       None.
