*=============================================================================
*
* Summary of the wcsutil routines
* -------------------------------
* Simple utility functions for internal use only by WCSLIB. They are
* documented here solely as an aid to understanding the code. They are not
* intended for external use - the API may change without notice!
*
*
* wcsutil_blank_fill() - Fill a character string with blanks
* ----------------------------------------------------------
* INTERNAL USE ONLY.
*
* wcsutil_blank_fill() pads a character string with blanks starting with the
* terminating NULL character.
*
* Used by the Fortran wrapper functions in translating C character strings
* into Fortran CHARACTER variables.
*
* Given:
* n int Length of the character array, c[].
*
* Given and returned:
* c char[] The character string. It will not be null-terminated
* on return.
*
* Function return value:
* void
*
*
* wcsutil_null_fill() - Fill a character string with NULLs
* --------------------------------------------------------
* INTERNAL USE ONLY.
*
* wcsutil_null_fill() strips off trailing blanks and pads the character array
* holding the string with NULL characters.
*
* Used mainly to make character strings intelligible in the GNU debugger which
* prints the rubbish following the terminating NULL, obscuring the valid part
* of the string.
*
* Given:
* n int Number of characters.
*
* Given and returned:
* c char[] The character string.
*
* Function return value:
* void
*
*
* wcsutil_allEq() - Test for equality of a particular vector element
* ------------------------------------------------------------------
* INTERNAL USE ONLY.
*
* wcsutil_allEq() tests for equality of a particular element in a set of
* vectors.
*
* Given:
* nvec int The number of vectors.
*
* nelem int The length of each vector.
*
* first const double*
* Pointer to the first element to test in the array.
* The elements tested for equality are
*
= *first == *(first + nelem)
= == *(first + nelem*2)
= :
= == *(first + nelem*(nvec-1));
*
* The array might be dimensioned as
*
= double v[nvec][nelem];
*
* Function return value:
* int Status return value:
* 0: Not all equal.
* 1: All equal.
*
*
* wcsutil_setAll() - Set a particular vector element
* --------------------------------------------------
* INTERNAL USE ONLY.
*
* wcsutil_setAll() sets the value of a particular element in a set of vectors.
*
* Given:
* nvec int The number of vectors.
*
* nelem int The length of each vector.
*
* Given and returned:
* first double* Pointer to the first element in the array, the value
* of which is used to set the others
*
= *(first + nelem) = *first;
= *(first + nelem*2) = *first;
= :
= *(first + nelem*(nvec-1)) = *first;
*
* The array might be dimensioned as
*
= double v[nvec][nelem];
*
* Function return value:
* void
*
*
* wcsutil_setAli() - Set a particular vector element
* --------------------------------------------------
* INTERNAL USE ONLY.
*
* wcsutil_setAli() sets the value of a particular element in a set of vectors.
*
* Given:
* nvec int The number of vectors.
*
* nelem int The length of each vector.
*
* Given and returned:
* first int* Pointer to the first element in the array, the value
* of which is used to set the others
*
= *(first + nelem) = *first;
= *(first + nelem*2) = *first;
= :
= *(first + nelem*(nvec-1)) = *first;
*
* The array might be dimensioned as
*
= int v[nvec][nelem];
*
* Function return value:
* void
*
*
* wcsutil_setBit() - Set bits in selected elements of an array
* ------------------------------------------------------------
* INTERNAL USE ONLY.
*
* wcsutil_setBit() sets bits in selected elements of an array.
*
* Given:
* nelem int Number of elements in the array.
*
* sel const int*
* Address of a selection array of length nelem. May
* be specified as the null pointer in which case all
* elements are selected.
*
* bits int Bit mask.
*
* Given and returned:
* array int* Address of the array of length nelem.
*
* Function return value:
* void
*
*
* wcsutil_fptr2str() - Translate pointer-to-function to string
* ------------------------------------------------------------
* INTERNAL USE ONLY.
*
* wcsutil_fptr2str() translates a pointer-to-function to hexadecimal string
* representation for output. It is used by the various routines that print
* the contents of WCSLIB structs. Note that it is not strictly legal to
* type-pun a function pointer to void*.
*
* See stackoverflow.com/questions/2741683/how-to-format-a-function-pointer
*
* Given:
* fptr int (*)() Pointer to function.
*
* Returned:
* hext char[] Null-terminated string. Should be at least 19 bytes
* in size to accomodate a 64-bit address (16 bytes in
* hex), plus the leading "0x" and trailing '\0'.
*
* Function return value:
* char * The address of hext.
