Name
intro - Introduction to Library Functions.
Synopsis
#include <ulib.h>
char* pname;
Description
This section introduces the set of Plan B library functions
for an application programmer. Most of the times only a sin-
gle header file has to be included, as shown in the synop-
sys. No other include is necessary unless stated so in the
synopsys of the manual page for the function considered.
Standard C library functions are considered part of the sys-
tem library and do not require extra includes.
When running on a hosted environment, the native system
libraries are also available.
pname is a global string containing the program name.
Diagnostics
All system calls and some library functions may raise excep-
tions; the error string describes the cause. See error(3)
for a description.

Bugs
None of the C library functions is document, and some Plan B
library functions lack their manual pages too.
Many library functions are missingnative ones are being
used instead. This is expected to change soon as applica-
tions are ported to Plan B.
