Fchgs, Fchgs32(3fml)
Name
Fchgs(), Fchgs32() - change field occurrence - caller presents string
Synopsis
#include <stdio.h>
#include "fml.h"
int
Fchgs(FBFR *fbfr, FLDID fieldid, FLDOCC oc, char *value)
#include "fml32.h"
int
Fchgs32(FBFR32 *fbfr, FLDID32 fieldid, int oc, char *value)
Description
Fchgs(), is provided to handle the case of conversion from 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. value is a pointer to the string to be added. The function calls its non-string-function counterpart, CFchg(), providing a type of FLD_STRING, and a len of 0 to convert from a string to the field type of fieldid.
Fchgs32() is used with 32-bit FML.
A thread in a multithreaded application may issue a call to Fchgs() or Fchgs32() 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, Fchgs() 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 value is to be added or changed in a fielded buffer but there is not enough space remaining in the buffer.
A field identifier is specified which is not valid.
A field identifier is specified which is not valid.
