Ffprint(), Ffprint32() - print fielded buffer to specified stream
Ffprint(FBFR *fbfr, FILE *iop)
Ffprint32(FBFR32 *fbfr, FILE *iop)
Ffprint() is similar to Fprint(), except the text is printed to a specified output stream. fbfr is a pointer to a fielded buffer. iop is a pointer of type FILE that points to the output stream.
For each field in the buffer, the output prints the field name and field value separated by a tab. Fname() is used to determine the field name; if the field name cannot be determined, then the field identifier is printed. Non-printable characters in string and character array field values are represented by a backslash followed by their two-character hexadecimal value. A newline is printed following the output of the printed buffer.
For values of type FLD_PTR, Ffprint32() prints the field name or field identifier and the pointer value in hexadecimal. Although this function prints pointer information, the Fextread32() function ignores the FLD_PTR field type.
For values of type FLD_FML32, Ffprint32() recursively prints the FML32 buffer, with leading tabs added for each level of nesting. For values of type FLD_VIEW32, Ffprint32() prints the VIEW32 field name and structure member name/value pairs.
Ffprint32() is used with 32-bit FML.
A thread in a multithreaded application may issue a call to Ffprint() or Ffprint32() while running in any context state, including TPINVALIDCONTEXT.
This function returns -1 on error and sets Ferror to indicate the error condition.
Under the following conditions, Ffprint() fails and sets Ferror to:
The buffer does not begin on the proper boundary.
The buffer is not a fielded buffer or has not been initialized by Finit().
Allocation of space dynamically using malloc() failed.
This function is not supported using the BEA Tuxedo System Workstation DLL for OS/2 and Microsoft Windows.
