+C Version +

+An ANSI C version of SLALIB is available from the author +but is not part of the Starlink release. +The functionality of this (proprietary) C version closely matches +that of the Starlink Fortran SLALIB, partly for the convenience of +existing users of the Fortran version, some of whom have in the past +implemented C ``wrappers''. The function names +cannot be the same as the Fortran versions because of potential +linking problems when +both forms of the library are present; the C routine which +is the equivalent of (for example) SLA_REFRO is slaRefro. +The types of arguments follow the Fortran version, except +that integers are int rather than long. +Argument passing is by value +(except for arrays and strings of course) +for given arguments and by pointer for returned arguments. +All the C functions are re-entrant. +

+The Fortran routines sla_GRESID, sla_RANDOM and +sla_WAIT have no C counterparts. +

+Further details of the C version of SLALIB are available +from the author. The definitive guide to +the calling sequences is the file slalib.h. +
