strstr – Find the first substring in a NUL terminated string Synopsis char *strstr(const char *s1, const char *s2); Arguments s1 The string to be searched s2 The string to search for Copyright

strspn – Calculate the length of the initial substring of s which only contain letters in accept Synopsis size_t strspn(const char *s, const char *accept); Arguments s The string to be searched accept The string to search for Copyright

strsep – Split a string into tokens Synopsis char *strsep(char **s, const char *ct); Arguments s The string to be searched ct The characters to search for Description strsep updates s to point after the token, ready for the next call. It returns empty tokens, too, behaving exactly like the libc function of that name….

strscpy – Copy a C-string into a sized buffer Synopsis ssize_t strscpy(char * dest, const char * src, size_t count); Arguments dest Where to copy the string to src Where to copy the string from count Size of destination buffer Description Copy the string, or as much of it as fits, into the dest buffer. The routine returns the number…

strreplace – Replace all occurrences of character in string. Synopsis char *strreplace(char *s, char old, char new); Arguments s The string to operate on. old The character being replaced. new The character old is replaced with. Description Returns pointer to the nul byte at the end of s. Copyright

strrchr – Find the last occurrence of a character in a string Synopsis char *strrchr(const char *s, int c); Arguments s The string to be searched c The character to search for Copyright

strpbrk – Find the first occurrence of a set of characters Synopsis char *strpbrk(const char *cs, const char *ct); Arguments cs The string to be searched ct The characters to search for Copyright

strnstr – Find the first substring in a length-limited string Synopsis char *strnstr(const char *s1, const char *s2, size_t len); Arguments s1 The string to be searched s2 The string to search for len the maximum number of characters to search Copyright

strnlen – Find the length of a length-limited string Synopsis size_t strnlen(const char *s, size_t count); Arguments s The string to be sized count The maximum number of bytes to search Copyright

strncpy – Copy a length-limited, C-string Synopsis char *strncpy(char *dest, const char *src, size_t count); Arguments dest Where to copy the string to src Where to copy the string from count The maximum number of bytes to copy Description The result is not NUL-terminated if the source exceeds count bytes. In the case where the…
