* Purpose:
* Implement a C interface to the Fortran SLALIB library.
* Description:
* This file implements a C interface to the Fortran version of the
* SLALIB library.
* Notes:
* This interface only supports a subset of the functions provided by
* SLALIB. It should be extended as and when necessary.

* Name:
* slaStringExport
* Purpose:
* Export a C string to a FORTRAN string.
* Type:
* Protected function.
* Synopsis:
* void slaStringExport( const char *source_c, char *dest_f, int dest_len )
* Description:
* This function creates a FORTRAN string from a C string, storing
* it in the supplied memory. If the C string is shorter than the
* space allocated for the FORTRAN string, then it is padded with
* blanks. If the C string is longer than the space allocated for
* the FORTRAN string, then the string is truncated.
* Parameters:
* source_c
* A pointer to the input C string.
* dest_f
* A pointer to the output FORTRAN string.
* dest_len
* The length of the output FORTRAN string.
* Notes:
* - This function is potentially platform-specific. For example,
* if FORTRAN strings were passed by descriptor, then the
* descriptor address would be passed as "dest_f" and this must
* then be used to locate the actual FORTRAN character data.
* - This function is equivalent to cnfExprt but is included here to
* avoid SLALIB becoming dependent on CNF.

* Name:
* slaStringImportt
* Purpose:
* Import a FORTRAN string into a C string
* Type:
* Protected function.
* Language:
* ANSI C
* Invocation:
* slaStringImport( source_f, source_len, dest_c )
* Description:
* Import a FORTRAN string into a C string, discarding trailing
* blanks. The NUL character is appended to the C string after
* the last non-blank character. The input string and output string
* pointers can point to the same location if the string is to be
* modified in place (but care must be taken to allow for the additional
* C terminator when allocating memory).
* Arguments:
* const char *source_f (Given)
* A pointer to the input FORTRAN string
* int source_len (Given)
* The length of the input FORTRAN string
* char *dest_c (Returned via pointer)
* A pointer to the output C string. Can be same as source.
* Notes:
* - No check is made that there is sufficient space allocated to
* the C string to hold the FORTRAN string and a terminating null.
* It is responsibility of the programmer to check this.
* - This function is equivalent to cnfImprt but is included here to
* avoid SLALIB becoming dependent on CNF.
