MathLink C Function


int MLPutByteString(MLINK link, const unsigned char *s, int n)
puts a string of n characters starting from location s to the MathLink connection specified by link.
  • All characters in the string must be specified using character codes as obtained from ToCharacterCode in Mathematica.
  • Newlines must thus be specified in terms of their raw character codes, rather than using \n.
  • MLPutByteString() handles only characters with codes less than 256.
  • It can handle both ordinary ASCII as well as ISO Latin-1 characters.
  • MLPutByteString() returns 0 in the event of an error, and a nonzero value if the function succeeds.
  • Use MLError() to retrieve the error code if MLPutByteString() fails.
  • MLPutByteString() is declared in the MathLink header file mathlink.h.
#include "mathlink.h"

        { /* unable to get the string from sourcelink */ }

    if(! MLPutByteString(destinationlink, string, length))
