---|
| 26 | DESCRIPTION |
---|
| 27 | <<vscanf>>, <<vfscanf>>, and <<vsscanf>> are (respectively) variants |
---|
| 28 | of <<scanf>>, <<fscanf>>, and <<sscanf>>. They differ only in |
---|
| 29 | allowing their caller to pass the variable argument list as a |
---|
| 30 | <<va_list>> object (initialized by <<va_start>>) rather than |
---|
| 31 | directly accepting a variable number of arguments. |
---|
| 32 | |
---|
| 33 | RETURNS |
---|
| 34 | The return values are consistent with the corresponding functions: |
---|
| 35 | <<vscanf>> returns the number of input fields successfully scanned, |
---|
| 36 | converted, and stored; the return value does not include scanned |
---|
| 37 | fields which were not stored. |
---|
| 38 | |
---|
| 39 | If <<vscanf>> attempts to read at end-of-file, the return value |
---|
| 40 | is <<EOF>>. |
---|
| 41 | |
---|
| 42 | If no fields were stored, the return value is <<0>>. |
---|
| 43 | |
---|
| 44 | The routines <<_vscanf_r>>, <<_vfscanf_f>>, and <<_vsscanf_r>> are |
---|
| 45 | reentrant versions which take an additional first parameter which points to the |
---|
| 46 | reentrancy structure. |
---|
| 47 | |
---|
| 48 | PORTABILITY |
---|
| 49 | These are GNU extensions. |
---|
| 50 | |
