Routines By Category
This section gives a brief overview of the major categories of library routines that are available in the C51 standard library.
Note
- Many of the routines in the C51 standard library are reentrant and/or intrinsic. These specifications are listed in the following tables. Unless otherwise noted, routines are non-reentrant and non-intrinsic.
