These functions get and setthat field..SH RETURN VALUEThe function \fBfield_userptr\fR returns \fBNULL\fR on error. The function\fBset_field_userptr\fR returns one of the following:.TP 5\fBE_OK\fRThe routine succeeded..TP 5\fBE_SYSTEM_ERROR\fRSystem error occurred (see \fBerrno\fR)..SH SEE ALSO\fBcurses\fR(3X), \fBform\fR(3X)..SH NOTESThe header file \fB<form.h>\fR automatically includes the header file\fB<curses.h>\fR..SH PORTABILITYThese routines emulate the System V forms library.  They were not supported onVersion 7 or BSD versions.The user pointer should be a void pointer.  We leave it as a char pointer forSVr4 compatibility..SH AUTHORSJuergen Pfeifer.
