## ProcedureSpiceInt bsrchc_c ( ConstSpiceChar * value, SpiceInt ndim, SpiceInt lenvals, const void * array ) ## AbstractDo a binary earch 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_ReadingNone. ## KeywordsARRAY, SEARCH ## Brief_I/OVARIABLE 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_Inputvalue 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 that 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_OutputThe function returns the index of the specified value in the input array. Array indices range from zero to ndim-1. If the input array does not contain the specified value, the function returns -1. If the input array contains more than one occurrence of the specified value, the returned index may point to any of the occurrences. ## ParametersNone. ## Exceptions1) 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. ## FilesNone ## ParticularsA binary search is performed on the input array. If an element of the array is found to match the input value, the index of that element is returned. If no matching element is found, -1 is returned. ## ExamplesLet array be a character array of dimension [5][lenvals] which contains the following elements: "BOHR" "EINSTEIN" "FEYNMAN" "GALILEO" "NEWTON" Then ## Restrictions1) The input array is assumed to be sorted in increasing order.
