Fboolpr(), Fboolpr32(), Fvboolpr(), Fvboolpr32() - print Boolean expression as parsed

#include <stdio.h> 
#include "fml.h" 
void 
Fboolpr(char *tree, FILE *iop) 
int 
Fvboolpr(char *tree, FILE *iop, char *viewname) 
#include "fml32.h" 
void 
Fboolpr32(char *tree, FILE *iop) 
int 
Fvboolpr32(char *tree, FILE *iop, char *viewname)

Fboolpr() prints a compiled expression to the specified output stream. The evaluation tree, tree, is one previously created with Fboolco(). iop is a pointer of type FILE to the output stream. The output is fully parenthesized, as it was parsed (as indicated by the evaluation tree). The function is useful for debugging.

Fboolpr32() is used with 32-bit FML.

Fvboolpr() and Fvboolpr32() provide the same functionality for views. The viewname parameter indicates the view from which the field offsets are taken, and should be the same view specified for Fvboolco() or Fvboolco32().

These functions are not supported on Workstation platforms.

A thread in a multithreaded application may issue a call to any of the functions documented here-Fboolpr(), Fboolpr32(), Fvboolpr(), or Fvboolpr32()-while running in any context state, including TPINVALIDCONTEXT.

Fboolpr() is declared as returning a void, so there are no return values. Fvboolpr() returns -1 if the view name is not valid.

Under the following conditions, Fvboolpr() fails and sets Ferror to:

[FBADVIEW]

"cannot find or get view"
viewname was not found in the files specified by VIEWDIR or VIEWFILES.

[FVFOPEN]

"cannot find or open view file"
While trying to find viewname, the program failed to find one of the files specified by VIEWDIR or VIEWFILES.

[EUNIX]

"operating system error"
While trying to find viewname, the program failed to open one of the files specified by VIEWDIR or VIEWFILES for reading.

[FVFSYNTAX]

"bad viewfile"
While trying to find viewname, one of the files specified by VIEWDIR or VIEWFILES was corrupted or not a view file.

[FMALLOC]

"malloc failed"
While trying to find viewname, malloc() failed while allocating space to hold the view information.

This function is not supported using the BEA Tuxedo System Workstation DLL for OS/2 and Microsoft Windows.
