AVR–specific library functions

Reference Guide

strcpy_P

char * strcpy_P(char *s1, PGM_P s2);

Identical to 

strcpy

 except that the string 

s2

 being copied is in flash memory, not in data 

memory. This function is available in both the CLIB and the DLIB library.

strerror_P

PGM_P strerror_P(int errnum);

Identical to 

strerror

 except that the string returned is in flash memory, not in data 

memory. This function is available in both the CLIB and the DLIB library.

strlen_G

size_t strlen_G(const char _ _generic *s);

Identical to 

strlen

 except that the string being tested can be in flash or data memory. 

This function is only available in the DLIB library.

strlen_P

size_t strlen_P(PGM_P s);

Identical to 

strlen

 except that the string being tested is in flash memory, not in data 

memory. This function is available in both the CLIB and the DLIB library.

strncat_G

char *strncat_G(char *s1, const char _ _generic *s2, size_t n);

Identical to 

strncmp

 except that the string 

s2

 can be in flash or data memory. This 

function is only available in the DLIB library.

strncmp_G

int

 

strncmp_G(const

 

char *s1,

 

const

 

char

 

_ _generic

 

*s2,

 

size_t

 

n);

Identical to 

strncmp

 except that the string 

s2

 can be in flash or data memory. This 

function is only available in the DLIB library.

strncmp_P

int strncmp_P(const char *s1, PGM_P s2, size_t n);

Identical to 

strncmp

 except that the string 

s2

 is in flash memory, not in data memory. 

This function is available in both the CLIB and the DLIB library.

strncpy_G

char *strncpy_G(char *s1, const char _ _generic *s2, size_t n);

Identical to 

strncpy

 except that the source string 

s2

 can be in flash or data memory. 

This function is only available in the DLIB library.
