are secretly a wrapper around this function. vgprintf does not
|
||||
implement all the filters supported by printf, only those that are
|
||||
currently used by fish. vgprintf internally uses snprintf to
|
||||
implement the %f %d and %u filters.
|
||||
implement the number outputs, such as %f and %x.
|
||||
|
||||
Currently supported functionality:
|
||||
|
||||
- precision specification, both through .* and .N
|
||||
- width specification through * and N
|
||||
- Padding through * and N
|
||||
- Right padding using the - prefix
|
||||
- long versions of all filters thorugh l and ll prefix
|
||||
- Character outout using %c
|
||||
- Character output using %c
|
||||
- String output through %s
|
||||
- Floating point number output through %f
|
||||
- Integer output through %d or %i
|
||||
- Unsigned integer output through %u
|
||||
- Left padding using the - prefix
|
||||
- Integer output through %d, %i, %u, %o, %x and %X
|
||||
|
||||
For a full description on the usage of *printf, see use 'man 3 printf'.
