No API References for CCS, could anyone send me API Guide? Thanks a lot !!!!!!

Hello, everyone! I recently study the implementation for very large FFT of  signals  in Multicore DSP (C6678) and read the program that was distributed by the Texas Instruments. In the program, I ran into some problems of understanding the basic APIs that were used for the algorithms, for example, 

void transpose_2Cols_rowsX8_cplxMatrix_sa ( float *pIn, float *pOut, Uint32 rows );

 void DSPF_sp_radix4_fftSPxSP( Uint32 n, float *pIn, float *pTwiddle, float *pOut, Uint32 log4NMinus1 );   

void transpose_2Rows_8XCols_cplxMatrix_sa ( float *pIn, float *pOut, Uint32 cols );

........

There are many such that APIs that I don't know what the arguments in it stand for, and the result of it means. Could anyone show me how to look up these APIs, or maybe there is API guide of the DSP for CCv5? Please tell me where to find the references guide of these APIs?  Thank you very much!!!!

By the way, there is not any reference in the  dsplib _c66x_3_1_1_1 packages........

    Hi Kang,

    Have you checked the User Guide in the docs folder of DSPLIB 3.1.1 package. Click on the API reference link in that html page to look at description of APIs and their arguments. another option if the DSPLIB was discovered as an eclipse plug in in your CCS version, you should be able to open the DSPLIB reference guide by going into CCS->Help menu.

    Let us know if you still have any issues.

    Regards,

    Rahul

    Thanksk for your answer, Rahul Prabhu. I have tried to look up these functions in the DSPLIB 3.1.1 and search the API references in the html page, but didn't find these APIs,and in the help menu no such APIs either.....

    But these functions run correctly in the program!
