MATHEMATICA MATHLINK C FUNCTION
MLPutByteString()
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.
DetailsDetails
- 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.
