82 Support for these requires malloc/free along with a handful of
83 POSIX-compatible functions:
92 disabled by specifying `-Dposix-io=false` in the meson command line.
102 ### malloc and free
104 Both versions of malloc in picolibc require sbrk to be supported. The
105 smaller version, enabled (by default) with -Dnewlib-nano-malloc=true,
106 can handle sbrk returning dis-continuous memory while the larger
107 version (enabled with -Dnewlib-nano-malloc=false) requires sbrk return
113 memory from a pre-defined contiguous heap. To use this function, your
129 calls `_exit` for uncaught and un-ignored signals.
139 `--oslib=` parameter:
141 $ gcc -o program.elf program.o --oslib=myos
143 This will include -lmyos after -lc so that the linker can resolve
151 For RISC-V and ARM processors, Picolibc provides an implementation of
156 application using `--oslib=semihost` in your link command line.
164 As a build-time option, Picolibc can be configured to use POSIX read
166 `-Dposix-console=true` to enable this. This is incompatible with
173 configuration, picolibc provides the non-POSIX libc APIs while the
