The Linux Manuals (man pages) document is an important part of Linux documents. Linux Manuals are organized as several sections. Each section has a group of commands for a specific area in Linux usage, administration or development.
std::strftime – std::strftime Synopsis Defined in header<ctime> std::size_t strftime(char *str, std::size_t count, const char *format, const std::tm *time); Converts the date and time information from a given calendar time time to a null-terminated multibyte character string str according to format string format. Up to count bytes are written. Parameters str – pointer to the first…
std::strerror – std::strerror Synopsis Defined in header<cstring> char *strerror(int errnum); Returns a pointer to the textual description of the system error code errnum, identical to the description that would be printed by std::perror(). errnum is usually acquired from the errno variable, however the function accepts any value of type int. The contents of the string…
std::streamsize – std::streamsize Synopsis Defined in header <ios> typedef /*unspecified*/ streamsize; The type std::streamsize is a signed integral type used to represent the number of characters transferred in an I/O operation or the size of an I/O buffer. It is used as a signed counterpart of std::size_t, similar to the POSIX type ssize_t. Except in…
std::streamoff – std::streamoff Synopsis Defined in header <ios> typedef /*unspecified*/ streamoff; The type std::streamoff is a signed integral type of sufficient size to represent the maximum possible file size supported by the operating system. Typically, this is a typedef to long long. It is used to represent offsets from stream positions (values of type std::fpos)….
std::basic_streambuf – std::basic_streambuf Synopsis Defined in header <streambuf> template< class CharT, class Traits = std::char_traits<CharT> > class basic_streambuf; The class basic_streambuf controls input and output to a character sequence.

std::strcspn – std::strcspn Synopsis Defined in header<cstring> size_t strcspn(const char *dest, const char *src); Returns the length of the maximum initial segment of the byte string pointed to by dest, that consists of only the characters not found in byte string pointed to by src. The function name stands for "complementary span" Parameters dest –…
std::strcpy – std::strcpy Synopsis Defined in header<cstring> char *strcpy(char *dest, const char *src); Copies the character string pointed to by src, including the null terminator, to the character array whose first element is pointed to by dest.

std::strcmp – std::strcmp Synopsis Defined in header<cstring> int strcmp(const char *lhs, const char *rhs); Compares two null-terminated byte strings lexicographically. The sign of the result is the sign of the difference between the values of the first pair of characters (both interpreted as unsigned char) that differ in the strings being compared. The behavior is…
std::strchr – std::strchr Synopsis Defined in header<cstring> const char *strchr(const char *str, int ch); char *strchr(char *str, int ch); Finds the first occurrence of the character static_cast<char>(ch) in the byte string pointed to by str. The terminating null character is considered to be a part of the string and can be found if searching for…
std::strcat – std::strcat Synopsis Defined in header<cstring> char *strcat(char *dest, const char *src); Appends a copy of the character string pointed to by src to the end of the character string pointed to by dest. The character src[0] replaces the null terminator at the end of dest. The resulting byte string is null-terminated. The behavior…
