Fgets, Fgets32(3fml)
Name
Fgets(), Fgets32() - get value converted to string
Synopsis
#include <stdio.h>
#include "fml.h"
int
Fgets(FBFR *fbfr, FLDID fieldid, FLDOCC oc, char *buf)
#include "fml32.h"
int
Fgets32(FBFR32 *fbfr, FLDID32 fieldid, FLDOCC32 oc, char *buf)
Description
Fgets() retrieves a field occurrence from the fielded buffer first converting the value to a user type of FLD_STRING. fbfr is a pointer to a fielded buffer. fieldid is a field identifier. oc is the occurrence number of the field. The caller of Fgets() provides buf, a pointer to a private buffer, which is used for the retrieved field value. It is assumed that buf is large enough to hold the value. Basically, Fgets() calls CFget() with an assumed utype of FLD_STRING, and a ulen of 0.
Fgets32() is used with 32-bit FML.
A thread in a multithreaded application may issue a call to Fgets() or Fgets32() while running in any context state, including TPINVALIDCONTEXT.
Return Values
This function returns -1 on error and sets Ferror to indicate the error condition.
Errors
Under the following conditions, Fgets() 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().
A field occurrence is requested but the specified field and/or occurrence was not found in the fielded buffer.
A field identifier is specified which is not valid.
A field identifier is specified which is not valid.
Allocation of space dynamically using malloc() failed.
