Code enabled by |
|
fs_api..c |
Application |
FS_CFG_API_EN |
Test error indicator on a file.
Arguments
p_file
Pointer to a file.
Returned Value
0, if error indicator is not set or if an error occurred
Non-zero value, if error indicator is set.
Notes/Warnings
The return value from this function should ALWAYS be tested against 0:
|
rtn = fs_ferror(p_file); if (rtn == 0) { // Error indicator is NOT set } else { // Error indicator is set } |
If the error indicator is set (i.e., fs_ferror() returns a non-zero value), fs_clearerr() can be used to clear that indicator.
