Functions

haddextension char* haddextension(kstring_t* buffer, const(char)* filename, int replace, const(char)* extension): @param buffer The kstring to be used to store the modified filename @param filename The filename to be (copied and) adjusted @param replace If non-zero, one extension (if any) is removed first @param extension The extension to be added (e.g. ".csi") @return The modified filename (i.e., buffer->s), or NULL on error. @since 1.10
hclearerr void hclearerr(hFILE* fp): Clear the stream's error indicator
hclose int hclose(hFILE* fp): @return 0 if successful, or EOF (with _errno_ set) if an error occurred.
hclose_abruptly void hclose_abruptly(hFILE* fp): For use while cleaning up after an error only. Preserves _errno_.
hdopen hFILE* hdopen(int fd, const(char)* mode): @return An hFILE pointer, or NULL (with _errno_ set) if an error occurred.
herrno int herrno(hFILE* fp): @return Non-zero (in fact, an _errno_ value) if an error has occurred.
hfile_mem_get_buffer char* hfile_mem_get_buffer(hFILE* file, size_t* length): @return buffer if successful, or NULL if an error occurred
hfile_mem_steal_buffer char* hfile_mem_steal_buffer(hFILE* file, size_t* length): @return buffer if successful, or NULL if an error occurred
hfile_set_blksize int hfile_set_blksize(hFILE* fp, size_t bufsiz): set hfile blocksize
hflush int hflush(hFILE* fp): @return 0 if successful, or EOF if an error occurred.
hgetc int hgetc(hFILE* fp)
hgetc2 int hgetc2(hFILE* ): @return The character read, or EOF on end-of-file or error.
hgetdelim ssize_t hgetdelim(char* buffer, size_t size, int delim, hFILE* fp): @param buffer The buffer into which bytes will be written @param size The size of the buffer @param delim The delimiter (interpreted as an unsigned char) @param fp The file stream @return The number of bytes read, or negative on error. @since 1.4
hgetln ssize_t hgetln(char* buffer, size_t size, hFILE* fp): @param buffer The buffer into which bytes will be written @param size The size of the buffer @param fp The file stream @return The number of bytes read, or negative on error. @since 1.4
hgets char* hgets(char* buffer, int size, hFILE* fp): @param buffer The buffer into which bytes will be written @param size The size of the buffer (must be > 1 to be useful) @param fp The file stream @return _buffer_ on success, or NULL if an error occurred. @since 1.4
hisremote int hisremote(const(char)* filename): @return 0 if local, 1 if remote.
hopen hFILE* hopen(const(char)* filename, const(char)* mode, ...): @return An hFILE pointer, or NULL (with _errno_ set) if an error occurred.
hpeek ssize_t hpeek(hFILE* fp, void* buffer, size_t nbytes): @param fp The file stream @param buffer The buffer to which the peeked bytes will be written @param nbytes The number of bytes to peek at; limited by the size of the internal buffer, which could be as small as 4K. @return The number of bytes peeked, which may be less than _nbytes_ if EOF is encountered; or negative, if there was an I/O error.
hputc int hputc(int c, hFILE* fp)
hputc2 int hputc2(int , hFILE* ): @return The character written, or EOF if an error occurred.
hputs int hputs(const(char)* text, hFILE* fp)
hputs2 int hputs2(const(char)* , size_t , size_t , hFILE* ): @return 0 if successful, or EOF if an error occurred.
hread ssize_t hread(hFILE* fp, void* buffer, size_t nbytes)
hread2 ssize_t hread2(hFILE* , void* , size_t , size_t ): @return The number of bytes read, or negative if an error occurred.
hseek off_t hseek(hFILE* fp, off_t offset, int whence): @return The resulting offset within the stream (as per lseek(2)), or negative if an error occurred.
htell off_t htell(hFILE* fp): @return The offset within the stream, starting from zero.
hwrite ssize_t hwrite(hFILE* fp, const(void)* buffer, size_t nbytes)
hwrite2 ssize_t hwrite2(hFILE* , const(void)* , size_t , size_t ): @return Either _nbytes_, or negative if an error occurred.

Structs

hFILE struct hFILE: The fields of this structure are declared here solely for the benefit of the hFILE-related inline functions. They may change in future releases. User code should not use them directly; you should imagine that hFILE is an opaque incomplete type.
hFILE_backend struct hFILE_backend: internal
kstring_t struct kstring_t: Undocumented in source but is binding to C. You might be able to learn more by searching the web for its name.
