* Name: obstack_printf
|
||
|
|
*
|
||
|
|
* Description:
|
||
|
|
* This is similar to the asprintf except it uses obstack to allocate
|
||
|
|
* string on. The characters are written onto the end of the currently
|
||
|
|
* growing object and terminated by null byte.
|
||
|
|
*
|
||
|
|
* This function is defined in stdio.h in GlibC. There is no definition
|
||
|
|
* that would be in stdio.h required for these here and thus it is easier
|
||
|
|
* to just keep these functions here as user has to include obstack anyway
|
||
|
|
* to get the full functionality.
|
||
|
|
*
|
||
|
|
* Input Parameters:
|
||
|
|
* h: pointer to the handle used to grow the object.
|
||
|
|
* fmt: format string with its format inputs followed.
|
||
|
|
*
|
||
|
|
* Returned Value:
|
||
|
|
* Number of characters added to the obstack excluding the null byte.
