Documentation Errata for VisualDSP++ 5.0 C/C++ Compiler and Library Manual for TigerSHARC Processors (Revision 4.1, August 2008)

As shown in the Output window and in Help, error codes sometimes begin with a leading zero (for example, cc0025). If you try to suppress error codes with -W{error|remark|suppress|warn} or #pragma diag() and supply the code with a leading zero, it will not work. This is because the compiler reads the number as an octal value, and will suppress a different warning or error.

On page 1-280, change from:

The default heap, seg_heap, is always 0 and the primary heap IDs of user-defined heaps are 1 with any additional user-defined heaps being 2, 3, and so on, with each heap index being an increment of one from the previous heap index.

The default heap, seg_heap, is always 0 and the alternate heap is always 1 with any additional user-defined heaps being 2, 3, and so on, with each heap index being an increment of one from the previous heap index.

You should not initialize a heap at runtime with the same id as a statically defined heap, including the default heap and alternate heap (with ids 0 and 1, respectively) if they are present.

Each filter should have its own delay line which is a vector of type float and whose length is equal to the number of coefficients.

Each filter should have its own delay line which is a vector of type float and whose length is equal to the number of coefficients per polyphase filter.

float delay[NCOEFFS];

float delay[NCOEFFS/NPOLY];

/* Initialize the delay line */
for (i = 0; i < NCOEFFS; i++)
      delay[i] = 0;

• In the 5th paragraph (The length modifier can be used to specify ...), remove the character sequence e, f, g, from the 2nd sentence (The length modifiers should only precede ...).
• Following the 5th paragraph (The length modifier can be used to specify the size of the ...) Table 3-29. (Length Modifier for fscanf) documents the length modifiers h and l and ll and L. Replace this table with the corresponding table in the Blackfin manual (on page 3-163).
• Insert the following paragraph immediately after the above-mentioned table:

  Note that the hh, j, t, and z size specifiers are defined in the C99 (ISO/IEC 9899:1999) standard.

• The following symbols in the new paragraph should be in Letter Gothic font: hh, j, t, z

If the heap_index is the current heap then heap_index is returned, otherwise a value of -1 is returned.

If the current heap was previously set then the index of the previous heap is returned, otherwise -1 is returned.
