The C standards require it to do this, in addition to calling fseek. Here is a test that can show the issue (in a realistic program, the indicator would be set due to an actual IO error, but for testing purposes this just sets it explicitly): #include <stdio.h> int main(void) { FILE *f = tmpfile(); if (!f) return 0; f->_flag |= _IOERR; if (!ferror(f)) puts("bad ferror"); rewind(f); if (ferror(f)) puts("rewind does not reset ferror"); fclose(f); } |

ORCALib
Libraries for the ORCA language suite (ORCA/C, ORCA/M, ORCA/Pascal) for the Apple IIGS
If you would like to make changes to this compiler and distribute them to others, feel free to submit them here. If the changes apply to the Apple IIGS, they will generally be approved for distribution on the master branch. For changes that retarget the library to generate code for a different platform, the project will either be forked or a new repository will be created, as appropriate.
The general conditions that must be met before a change is released on master are:
-
The modified library must compile under the currently released version of ORCA/M.
-
The various languages that make use of the library mush still pass their respective test suites, or changes to those test suites must also be submitted.
Contact support@byteworks.us if you need contributor access.
A complete distribution of the ORCA languages, including installers and documentation, is available from the Juiced GS store at https://juiced.gs/store/category/software/. It is distributed as part of the Opus ][ package.
